NO. You are not reading the documentation for "if" carefully enough,
despite several efforts to point you in the right direction. You
cannot make literal transliterations of SPSS syntax work in the manner
you imagine.

Hello,
I'm using SPSS at work but really would like to switch to R. Right
now I'm
trying to learn R in reproducing calculations I did with SPSS but
am stuck
with something that is quite simple and comprehensible in SPSS-
Syntax:
IF (variable1.fac = 0 AND variable2.num = 0) variable3=1.
IF (variable1.fac = 0 AND variable2.num>= 1) variable3=2.
IF (variable1.fac = 1 AND variable2.num = 0) variable3=3.
IF (variable1.fac = 1 AND variable2.num>= 1) variable3=4.
I want to create four different groups out of different conditions
of two
variables:
* variable1.fac is a factor coded with 0 and 1
* variable2.num is a numerical variable with only whole numbers
My problem with R is that I can't find a way to use AND in an IF
statement
that doesn't produce an error or not intended solutions.
"An Introduction to R" is really unhelpful with this problem and I
wouldn't
have written here, if I didn't have searched for the answer.
http://tolstoy.newcastle.edu.au/R/help/05/09/12136.html was helpful
in
understanding how the IF statement is written in R but didn't
answer my
question how to add an usable AND (&, |)
https://stat.ethz.ch/pipermail/r-help/2008-November/178808.html
looked
promising but didn't do what I had intended
Thanks in advance,
Richard
