Hi,
I would like to write a little automatic routine in R, but i am a too much of a beginner for that. I will appreciate any help regarding this particular problem.
If all columns of your data.frame are numeric:
z[z<0] <- 0 z[z>1] <- 1
For added fun, you can wrap any of the methods given on the list into a function. For example:
hardLimit <- function(z, min=0, max=1){
z[z < min] <- min
z[z > max] <- max
return(z)
}Then you can do:
z <- hardLimit(z)
if you want to overwrite z, or:
y <- hardLimit(z)
to create a new data frame.
Note how the default min and max arguments are 0 and 1, and make the function more flexible. You can also do:
x <- hardLimit(z, min=-1)
and that sets everything below -1 to the value -1.
Welcome to the world of R development!
