[R] if else lop
I am trying to use if...else loop and have included a code snippet which I
might like to expand.
Maybe you could steer me in the right direction.
library(stats)
library(prob)
{
a - sample ( 1:4,100, replace=T,prob=c(0.1,0.2,0.5,0.3))
b-sample(3:6,100,replace=T,prob=c(0.2,0.2,0.2,0.4))
}
dd - data.frame(a,b)
if (subset finds a vector) ( print that vector)
(else continue looking at subsets)
subset(dd,isin(dd,c(1,4), ordered = FALSE))
subset(dd,isin(dd,c(3,3),ordered=F))
Thank you
G

Gary,
Was the second half of my message this morning not clear enough?
It wasn't clear from your original message that you were using isin()
from the prob package, rather than using isin() as pseudocode, so I'd
written a function to do that part. But the second half of my message
went through the if() part of your question. If it doesn't do what you
want, you need to be clearer about what you need that it doesn't do.

Hi Peter: Beware that gnashing of teeth business. My Dad, a dentist, said that a couple of his patients who were musicians did this when they played and ground their teeth down so much he had to make them dentures! ;-) Cheers, Bert On Tue, Jul 5, 2011 at 2:53 PM, peter dalgaard pda...@gmail.com wrote: On Jul 5, 2011, at 22:27 , gary engstrom wrote: I am trying to use if...else loop Argh! hurting of eyes and gnashing of teeth A loop goes _around_ and around. for, repeat, while. if ... else is a _branching_ construct. -- Peter Dalgaard Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark Phone: (+45)38153501 Email: pd@cbs.dk Priv: pda...@gmail.com __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. -- Men by nature long to get on to the ultimate truths, and will often be impatient with elementary studies or fight shy of them.
