Dear Sir / Madam,
I am using R Programming Language Version 2.15.1 (2012-06-22) for sometime
in a 32 bit PC running Windows OS (Platform: i386-pc-mingw32/i386
(32-bit)).
During the execution / interpretation of the R script, sometimes it is
found that behavior of the program is not consistent with the program
structure.
For example, it has been seen that, even if a condition inside an IF
statement is not TRUE, the sequence of statements enclosed by parentheses {
}, which follows IF statement is executed. And this should not be the case.
May I know the exact reason for such kind of Erroneous behavior of the R
program?
Most likely user error. You are asked to provide a coded example to support any behavior that you suspect to be a bug. At the moment the "betting money" (colloquial English for an informed Bayesian prior) appears to be that you are making a test for numerical equality and don't really understand how to do this properly.
Is it the flaw in the Design of R Interpreter or there is some other reason behind that? Though as a user of R Programming Language, I understand that R is free software and comes with ABSOLUTELY NO WARRANTY.
In particular there is no warranty that user errors will be detected.
