Re: [R] Error Awareness

Stephen, It is becoming a pattern here. You have been told R allows ways to check for errors as the code is interpreted and this DOES NOT distinguish between development aspects and in the field. It does not matter if a problem is external like a required file not being in place or having a new n

Re: [R] .Rdata not loading

Three things you might try using R (and show the results in this email thread): * load(verbose=TRUE, ".RData") # see how far it gets before stopping * file.info(normalizePath(".RData")) # is this the file you think it is? * dput(readBin(".RData", what=raw(), n=100)) The last will print some hex n

Dear All. Warm greetings to you. I need help in solving an optimization formulation in R software. I tried to solve it in excel solver but it was going up to local minimum using GRG nonlinear solving method. I thought R can help in solving this problem so I am explaining the problem in few sentenc

You still are not exhibiting signs of understanding Bert's response, and your question is vague, particularly to the extent that it could be pertinent to the R language (and therefore to the topic of this list). R itself just raises an error condition that custom tryCatch or default handling wil

Re: [R] Error Awareness

Hi Bert, Thanks for the reply. The use case I presented involves working code, not diagnosing a script in development. The concern is running a script where something changes outside of the script, as I stated. An example of a change is a data source changing perhaps the columns in the dat

Hi, I am thinking about awareness of errors when an R script runs. My concern is I have an error-free script. I run it for months on end without problems. Then, something changes somewhere causing an error. My wonderment is how R will tell me I had an error in the script, but the rest of the
