readline() is reading the entire line and not just the user input
Seems to work fine with RTERM under my Windows:
ANSWER <- readline(prompt="Are you a satisfied R user? ")
Are you a satisfied R user? yes
ANSWER
[1] "yes"
sessionInfo()
R version 2.8.1 (2008-12-22) i386-pc-mingw32

I just discovered readline to provide user input. It is working as one would expect in Rgui but not in Rterm. In Rterm it reads the entire line of code not just the user input. How do I fix and what is the issue that I should read about? Here is my two line script: ANSWER <- readline(prompt="Are you a satisfied R user? ") ANSWER So under RGUI one gets the following
ANSWER <- readline(prompt="Are you a satisfied R user? ")
Are you a satisfied R user? yes
ANSWER
[1] "yes" Under RTERM one gets
ANSWER <- readline(prompt="Are you a satisfied R user? ")yes
Are you a satisfied R user?
ANSWER
[1] "ANSWER <- readline(prompt=\"Are you a satisfied R user? \")yes" So I tried to hit enter after I saw the line in the terminal and this is what I got:
ANSWER <- readline(prompt="Are you a satisfied R user? ")
Are you a satisfied R user?
ANSWER
[1] "ANSWER <- readline(prompt=\"Are you a satisfied R user? \")" My R environment: Windows XP with service pack 3; R 2.8.1, tinn-R 2.2.0.2 Farrel Buchinsky
