fValueString {psychReport}

fValueString

Description

Returns required Latex formatted string for F(df1, df2) = XXX for R/knitr integration. For example, F(1, 23) = 3.45. Returns values to 2 sig decimal places.

Usage

fValueString(aovObj, effect)

Arguments

aovObj

Output from aov or ezANOVA (NB. ezANOVA must be called with detailed = TRUE)

effect

The effect within the ANOVA table to return

Value

character

Examples

# Example 1:
# create dataframe and add data with 2(Comp: comp vs. incomp) and 2(Side: left vs. right)
dat <- createDF(nVP = 20, nTrl = 1,
                design = list("Comp" = c("comp", "incomp"),
                              "Side" = c("left", "right")))

dat <- addDataDF(dat, RT = list("Comp:Side comp:left"    = c(500, 150, 100),
                                "Comp:Side comp:right"   = c(500, 150, 100),
                                "Comp:Side incomp:left"  = c(520, 150, 100),
                                "Comp:Side incomp:right" = c(520, 150, 100)))

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

fString <- fValueString(aovRT, "Comp")
fString <- fValueString(aovRT, "Comp:Side")
