Dear R users,
I need to rename the columns of a series of data frames. The names of the data frames and those of the columns need to be pulled from some vectors. I tried a couple of things but only got errors. What am I missing?
#---create data frame dframes <- c("a","b","c") assign(dframes[2],data.frame(11:20,21:30))
#---rename the columns cols <- c("one","two")
names(get(dframes[2])) <- cols
Error: couldn't find function "get<-"
It tells you that there is not function "get<-": you cannot assign into something you are calling with get()!
assign(dframes[2],data.frame(cols[1]=11:20,cols[2]=21:30))
Error: syntax error
Note the "[1]" in the name!
labels(get(dframes[2]))[[2]] <- cols
Same as above.
What you are really going to do is:
dframes <- c("a","b","c") cols <- c("one","two") df <- data.frame(11:20, 21:30) names(df) <- cols assign(dframes[2], df)

I'm using R 2.0.0 on Windows XP.
Thank you, b.
