Re: [R] Bind field of a list
Hello,
Thank you but I think not what I would like to get as an answer is the list
(x,v,n,m) + what you gave me could work for 2 fields but if I have
200...
What I want is a vectorize way to do
bindlists - function(x){
output = c();
for (i in 1:length(x))
{
output = c(output,x[[i]])
}
return(output)
}
Regards

Hi, Try this, unlist(test) or do.call(c, test) HTH, baptiste On 19 February 2010 15:19, statquant colin.uman...@barcap.com wrote: Hello all I am new in R and so easy stuff are difficult... let say that I have a list test - list(a=c(x,v),b=c(n,m)) how can I without a loop get test$a bind with test$b (obviously in real life their would be many fields) Cheers and thanks -- View this message in context: http://n4.nabble.com/Bind-field-of-a-list-tp1561676p1561676.html Sent from the R help mailing list archive at Nabble.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. __ 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.

Instead try:
c( sapply(test, [) )
The inner (implicit) loop gets you a matrix and the outer c() turns it
into the requested vector. You could have coerced the matrix to vector
with as.vector, too.

Hello all
I am new in R and so easy stuff are difficult...
let say that I have a list

how can I without a loop get test$a bind with test$b (obviously in real life
their would be many fields)
Cheers and thanks
