SUMMARY: readline() to vector
Thanks to all who answered my
question (appended to this message). Two solutions:
1. If the user answers with the 4 lim values (i.e., 10,20,1,100),
limStr <- readline("Enter xlim and ylim values: ");
lim <- as.numeric(unlist(strsplit(limStr, ",")));
2. If the user answers in R vector notation (i.e., c(10,20,1,100) )
limStr <- readline("Enter xlim and ylim values: ")
lim <- eval(parse(text=limStr)
Note...

lim <- readline("Enter xlim and ylim values: ")
then would like to use the values in lim for a plot:
plot(etc, xlim=lim[1:2],ylim=lim[3:4])
The problem is that lim is a character,i.e.,
"10,20,-10,50"
or
"c(10,20,-10,50)"
depending on the input to
