Examples

# Example 1
# create dataframe and add data with 3(Comp: neutral vs. comp vs. incomp) levels
dat <- createDF(nVP = 20, nTrl = 1,
                design = list("Comp" = c("neutral", "comp", "incomp")))

dat <- addDataDF(dat, RT = list("Comp neutral" = c(510, 150, 100),
                                "Comp comp"    = c(500, 150, 100),
                                "Comp incomp"  = c(520, 150, 100)))

# repeated measures ANOVA using ezANOVA
library(ez)
aovRT <- ezANOVA(dat, dv=.(RT), wid = .(VP), within = .(Comp),
                 return_aov = TRUE, detailed = TRUE)
aovRT <- aovTable(aovRT)

sphericityValue <- sphericityValueString(aovRT, "Comp")
