ugly loop
maybe you want something like this: x <- c(t(pt$x)) Best, --D ---- Dimitris Rizopoulos Ph.D. Student Biostatistical Centre School of Public Health Catholic University of Leuven Address: Kapucijnenvoer 35, Leuven, Belgium Tel: +32/16/336899 Fax: +32/16/337015 Web: http://www.med.kuleuven.ac.be/biostat/ http://www.student.kuleuven.ac.be/~m0390867/dimitris.htm ----- Original Message ----- From: "Bill Simpson" <William.Simpson at drdc-rddc.gc.ca> To: "r-help" <r-help at stat.math.ethz.ch> Sent: Friday, April 22, 2005 2:58 PM Subject: [R] ugly loop
The following code is slow and ugly:
count<-0
for(i in 1:nrow(ver))
for(j in 1:ncol(ver))
{
count<-count+1
x[count]<-pt$x[ver[i,j]]
y[count]<-pt$y[ver[i,j]]
z[count]<-pt$z[ver[i,j]]
}
Please help me make it better.
Thanks!
Bill
