Finally, I'm getting to a point in working with R where I would like to start
to add some smart and custom error handling.
Specifically, I would like to add custom error handling to my code for
source(...), read.table(...), and readLines(...)
For example, right now I have the following:
> postprocesspath<-c("C:/")
> postprocess_scriptname<-c("Bob.R")
> fullpostpocessingpath<-paste(postprocesspath, postprocess_scriptname, sep="")
> source(fullpostpocessingpath)
Error in file(file, "r", encoding = encoding) :
cannot open the connection
In addition: Warning message:
In file(file, "r", encoding = encoding) :
cannot open file 'C:/Bob.R': No such file or directory
Instead of the error shown above, I would just like to simply have the last
line "cannot open file 'C:/Bob.R': No such file or directory" Or, add my own
statement to the above, e.g.
##########################################################
##########################################################
[[elided Yahoo spam]]
##########################################################
##########################################################
I would like to do something similar for read.table(...) and readLines(...).
Is such a thing possible?
Thanks again.
