Quantitative Analysis Made Accessible

Contains a number of functions that serve two goals. First, to make R more accessible to people migrating from SPSS by adding a number of functions that behave roughly like their SPSS equivalents (also see < http://rosettastats.com>). Second, to make a number of slightly more advanced functions more user friendly to relatively novice users. The package also conveniently houses a number of additional functions that are intended to increase the quality of methodology and statistics in psychology, not by offering technical solutions, but by shifting perspectives, for example towards reasoning based on sampling distributions as opposed to on point estimates.

Userfriendlyscience contains a number of functions that serve two goals. First, to make R more accessible to people migrating from SPSS by adding a number of functions that behave roughly like their SPSS equivalents. Second, to make a number of slightly more advanced functions more user friendly to relatively novice users. The package also conveniently houses a number of additional functions that are intended to increase the quality of methodology and statistics in psychology, not by offering technical solutions, but by shifting perspectives, for example towards reasoning based on sampling distributions as opposed to on point estimates.

The package imports functions from many other packages, which is in line with its function as a 'wrapper package': USF aims to make many existing functions easier for users coming from SPSS, so sometimes a function is added when it saves the user just some data preparing.

The only publications where the package has been mentioned so far are available at:

http://ehps.net/ehp/index.php/contents/article/download/ehp.v16.i2.p56/1 http://ehps.net/ehp/index.php/contents/article/download/ehp.v16.i2.p70/25 http://www.tandfonline.com/doi/pdf/10.1080/17437199.2015.1124240

All are Open Access. Please cite the manual and/or one of these publications when you use the package.

0.4-0 2015-

0.3-0 2015-04-16

  • Fixed powerHist to finally show frequencies with scaled normal curve and density curve
  • Fixed a bug in 'oneway'; post-hoc tests now working better
  • The 'regr' function now also computes the confidence interval for R^2
  • Renamed scaleReliability to scaleStructure and improved it to also provide estimates assuming an ordinal level of measurement as well as hierarchical omega in addition to total omega

0.2-0 2015-02-27

  • New function associationMatrix() added, which takes a list of variables and generates a table with confidence intervals of their effect sizes
  • New functions freq(), oneway(), and regr() added, which behave similar to SPSS functions to generate frequency tables, oneway anovas, and do simple regression analyses
  • New function samplingDistribution() added, which allows quick generation of sampling distributions based on frequency information
  • Added didacticPlot(), which builds plots that are useful for watching what happens when doing null hypothesis significance tests
  • Added dataShape() so that e1071 is no longer needed for Skewness and Kurtosis in normalityAssessment()

0.1-2 2014-04-21

  • testRetestReliability() added to conveniently call both testRetestAlpha() and testRetestCES().
  • testRetestAlpha() and testRetestCES() added to compute the test-retest coefficient Alpha and the Coefficient of Equivalence and Stability (CES).

  • meanDiff.multi improved to generate a forest plot by default, with line at zero to show 'significant' deviations more clearly
  • dlvPlot improved to show better confidence intervals and take confidence level into account
  • getData() can now also read from .csv, .tsv, .xls, and .xlsx. If ROpenOffice from http://omegahat.org is installed, .ods can be read, too.
