Dear list members,
i try to use checkUsage from codetools to test my scripts and functions
for errors. The scripts warn me correctly in case I use an unbinded
variable but fail to do so in case I bind a value to it after its first
usage in the script. Both cases, however, would result in the same r
error. For example:
test = function() {
b = 2*a
return(b)
}
test2 = function() {
b = 2*a
a = 3
return(b)
}
library(codetools)
checkUsage(test)
checkUsage(test2)
Is this a bug? Is there any way to get checkUsage to detect coding
errors as in test2 ?
Thanks for your help
Jannis
