Hi Simon,
Let's see. If I wrap the code into a function:
reverse.df.elements<-function(df,pattern="i",newrange=c(3,1)) {
revlist<-grep(pattern,names(df),fixed=TRUE)
df[,revlist]<-sapply(df[,revlist],rescale,newrange)
return(df)
}
Then this might do the trick:
lapply(list1,reverse.df.elements,
Hi Jim, So that does the rescale part very efficiently. But I’d like to know
how to do that on each list element using lapply or llply. I have about 4 data
frames and a few other recodes to do so automating would be nice, rather than
applying your code to each individual list element.

Hi Simon,
How about this?
library(plotrix)
revlist<-grep("i",names(df),fixed=TRUE)
df[,revlist]<-sapply(df[,revlist],rescale,c(3,1))

Hi there: I have a list of data frames with identical variable names. I’d
like to reverse scale the same variables in each data.frame.
I’d appreciate any one’s suggestions as to how to accomplish this. Right now,
I’m working with the code at the very bottom of my sample data.
Thanks, Simon K
