with was to embed:
print("Loading required packages...")
if (!require("reshape")) { install.packages("reshape") }
if (!require("reshape")) {
? print("Could not install package 'reshape', please contact your
sysadmin.")
? return()
}
? in the code proper, and put together the package using package.skeleton()
and R CMD build.
? I'm guessing there's a better way to do this -- any suggestions?
