Hello -

I have read about a function, replace.df(), that is available in base R. It
seems ideal since it would allow me to replace specific columns in one data
frame with columns in another data frame, while keeping all other columns
intact. The problem is that replace.df() does not seem to exist as a
function. Can anyone confirm this or provide the library in which it is
located? If it does not exist, is there another way to perform this column
specific replacement?

practice <- read.csv("data.csv", header=T)
practice1 <- aggregate(practice[, c(8,9,10,11,12,27,28)],
by=list(practice$codenumber), FUN=function(x) sub("(.*):", "\\1.", x))
practice2 <- replace.df(practice, practice1, by=c("codenumber"),
cols=c(8,9,10,11,12,27,28))
>>Error: could not find function "replace.df"

Thank you.

Alecia
