Revision history for the R/broman package

Version 0.67-3, 2017-12-05:

Added function grayplot_na(). It's like grayplot, but includes boxes near the margins to show points that are missing x or y or both.

Added function vec2string() for turning a vector into a string with the items separated by commas and an "and". This is for use in R Markdown documents, to list a series of items.

Added function get_precision() for determining the precision of a number (the number of digits past the decimal point). I want to use this to compare two data sets with different amounts of rounding, to pick the more precise values.

Added function align_vectors() for aligning two vectors using their names attributes.

In grayplot(), have default be pch=21 and bg="lightblue" (that is, points that are lightblue with a black circle around them).

Version 0.66-2, 2017-10-24:

Add bgcolor argument to triplot(), to have the background of the rectangle be gray, by default.

Also change default background in grayplot() and theme_karl() from "gray80" to "gray90" (which is much less dark of a gray).

Fix bug in dotplot() in case that y has missing values (omit them).

Version 0.65-4, 2017-05-07:

In note() for RPushbullet, force 'body' to be non-empty, because we get an error otherwise. In done(), use body=NULL to avoid similar errors.

Version 0.65-3, 2017-05-04:

Added the function crayons() which is shorthand for brocolors("crayons"), but also can take a subset of color names, and uses grep to find partial matches. So you can use crayons("purple mountain") rather than brocolors("crayons")["Purple Mountain's Majesty"]

Version 0.65-2, 2017-02-21:

Fix problem with pushbullet_devices(); output of RPushbullet::pbGetDevices()$devices is now a data frame; code assumes it's a list.

Version 0.65-1: 2016-11-30:

Add 'mar' argument to excel_fig. (plot margins; passed to par())

Version 0.63-3, 2015-06-20:

Add "web" colors option (from http://clrs.cc) and an alternative set of Collaborative Cross colors to brocolors()

Add checks for ^C (user interrupt) in compare_rows().

Add data numbers and Numbers (numbers 1-20 spelled out in English; numbers in lower-case and Numbers capitalized)

Version 0.62-1, 2015-01-05:

Remove attachfile() and loadfile() as I don't use them and they cause CRAN headaches.

Version 0.61-3, 2015-11-21:

Add function maxabs() which just does max(abs(x)).

Version 0.61-2, 2015-11-15:

Add function dotplot() which is a simplified version of grayplot() for categorical x.

Add function jiggle() for horizontal jiggling, either "fixed" (deterministic, similar to the beeswarm package) or "random"; used in dotplot()

In grayplot(), have vlines and hlines follow from xlim and ylim, respectively, if they're provided.

Version 0.60-1, 2015-09-24:

Add function fac2num() for converting a factor to numeric.

Version 0.59-5, 2015-08-04:

Add function excel_fig() for making a figure that shows the contents of a matrix, as it might appear in Excel.

Add function pushbullet_devices() for getting list of active pushbullet devices.

Version 0.58-2, 2015-07-16:

Add function compare_rows(), for comparing rows in a numeric matrix, either by proportion mismatches or RMS difference.

Add function add_commas(), for adding commas in large numbers, like 91310 -> "91,310"

Version 0.57-5, 2015-07-06:

Add function stop_sending_errors(), the reverse of errors2pushbullet().

Version 0.57-3, 2015-06-25:

Allow use of col.lab in grayplot(), for coloring the axis titles.

Version 0.57-1, 2015-06-18:

Add function switchv(), a vectorized version of switch().

Version 0.56-1, 2015-06-04:

Add function openfile() for opening a file using system().

Version 0.55-3, 2015-04-27:

In theme_karl(), add black rectangle around the facet rectangles, too.

Version 0.55-2, 2015-04-22:

Add function theme_karl() (aka karl_theme()), with a ggplot2 theme that removes the tick boxes and adds a black border.

Version 0.54-3, 2015-03-05:

Delete functions get0() and get.() since there's going to be a get0 function in base R 3.2.0.

Version 0.54-2, 2015-02-12:

Add note() function, which is just a wrapper for RPushbullet::pbPost.

Version 0.49-6, 11/3/2014:

Added argument v_over_h to grayplot(), controlling whether horizontal gridlines are on top of the vertical ones or vice versa.

Revisions to grayplot for better treatment of case of missing y. To avoid gridlines, use vlines=NA and/or hlines=NA.

Version 0.39, 10/17/2012:

In Description file, added "Depends: R (>= 2.15.0)", since get0 uses paste0. I could use paste(..., sep=""), but...

Version 0.38, 10/4/2012:

Changed order of plotting of vertical and horizontal lines in
grayplot().  Also added ability to control the margin parameters
(spacing of axis labels and such).

Deleted the nqrank() function, as I've now placed it within

Version 0.28, 3/25/2010:

Slight change to nqrank, so that -Inf values are replaced by
10 *less* than the minimum of any finite values (rather than 10
*more* than that minimum).

Version 0.27, 11/6/2009:

Revised runningmean and runningratio so that the statistics can be
calculated at arbitrary locations.  Also revised them so that the
input do not need to have sorted positions.

Version 0.26, 10/26/2009:

Slight change to nqrank, to preserve the mean and SD.

Fixed a few links in the help files.

Revised h() to conform to a change in R.

Version 0.25, 8/11/2009:

but may be (if one uses the argument jitter=TRUE).

Version 0.24, 4/28/2009:

Updated license to GPL-3

Version 0.23, 11/20/2008:

Revised perm.test and paired.perm.test so that they can return the
actual permutation results (rather than just the p-value), though
the default is still to just return the p-value.

Fixed a bug in myround().

Version 0.22, 9/19/2008:

Revised attachfile and attachwork so that they return (invisibly)
TRUE/FALSE according to whether the file was found.

Also added an argument 'verbose'; if TRUE and the file can't be
loaded, a warning is given.

Version 0.21, 2/29/2008:

Added a function normalize() for doing quantile normalization.

Version 0.20, 1/18/2007:

Modified fisher() so that the p-value is Prop'n >= rather
than just >.

Added a similar function, chisq() for doing a chi-square test
with p-value calculated by simulation.  In 0.20-2, suppressed
warnings produced by chisq.test.

Version 0.19, 10/9/2007:

Added a function runningratio, for calculating
sum(numerator)/sum(denominator) in sliding window.

Fixed some errors in the help files.

Version 0.18, 9/20/2007:

Fixed a bug in loadwork().

Added a function mypairs(), similar to pairs() but producing only
the upper triangle.

Added a convert2hex() function.

Version 0.13, 12/8/2004

Added attachfile() and loadfile(), similar to loadwork() and

Version 0.12, 8/6/2004

Added little utility functions loadwork() and attachwork()
for loading or attaching .RData files of the form
"dir*/.RData", when * is an integer, and especially when
dir = "Work".

Version 0.11, 4/29/2002:

Added perm.test and paired.perm.test for getting p-values for a
two-sample t-statistic by permutation.

There was an obvious bug in the function fisher(), which is now

Version 0.10, 11/21/2001:

This is a package to contain miscellaneous R functions that I find

Currently, it contains functions to get SEs of sample quantiles,
a sampling version of fisher.test, a re-parse of the output of
qr(), simulation from a multivariate normal distribution, and
numerical integration by Simpson's rule.
