Hello,

I am trying to ask the user for which column their data is in, and then use
this information in a function.  So far I have:

data <- read.csv(file.choose(), header=TRUE)
col <- (winDialogString("Which column contains your data?",""))

and I want to be able to reference such as:

meas <- data$col

and use this meas in the function.

However, I can't seem to get this to work because the input is read into a
string, and I can't figure out how to convert this string to the vector
name that I want.

Any help is appreciated.
