Functions

filtRT & outliers

These two functions are designed to filter reaction times (or other dependent variables) by thresholds (minimum and/or maximum values) and/or standard deviations from the mean. These functions return the cleaned data frame as well as how many data were exclude by kind of filter.

The difference between filtRT and outliers is that filtRT uses outliers to filter the data base on different conditions (e.g. by subject and independent variables).

faov, ftt & fmsd

These functions allow to easily format for knitr/sweave results from an ANOVA (faov, computed with the ez package), a t test of Student (ftt) and simple a mean with its related standard deviation (fmsd).

The formatting is done according to the APA guidelines. Different options allow to add thed of Cohen, change the format, etc.

writeAOV

This function was designed to easily export an ANOVA result (from the ez package) into a csv file. The options allow to add descriptive statistics and/or posthoc analysis.

figtheme

This function return a ggplot graphic which better suits for publication with a white theme, bigger fonts, and a choice of brewer color set.
