R help - Mar 2013 - Feedback – Regarding R Programming Language Version 2.15.1 (2012-06-22) Usage

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?

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.

Your valuable remark and guidance will lead us to destiny.

With regards,

Yours faithfully,
SUJIT DAS

Please do not massively cross-post and provide a reproducible example
(search stack overflow or other sites for advice on how to do so)

I _guarantee_ you R is not broken in this sense.

 I would put money on the original post being the most eloquently
spoken yet obfuscated report of FAQ 7.31 ever.

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.

In particular there is no warranty that user errors will be detected.
