Details

Sometime, data are entered as levels in an incorrect order. Once converted to numeric values, this can lead to confusion. recoding of the data to the correct order is straightforward, if tedious.

Examples

temp <- bfi[1:100,1:5]
isvalue <- 1:6
newvalue <- psych::cs(one,two,three,four,five,six)
newtemp <- recode(temp,1:5,isvalue,newvalue)
newtemp  #characters
temp.num <- psych::char2numeric(newtemp) #convert to numeric
temp.num  #notice the numerical values have changed
new.temp.num <- recode(temp.num, 1:5, isvalue=c(3,6,5,2,1,4), newvalue=1:6)
#note that because char2numeric works colum wise, this will fail for small sets
