Hi, I have a data set with 1000 observations and 260 predictors. The predictor variables are all ordinal. There are 2 classes labeled as, F and T with class proportions of 0.44 and 0.56, respectively. In a call to the function randomForest() with mytry=1 and nodesize=1 and ntree=100 the resulting classifier puts all observations in class T. When I change nodesize to nodesize=5 I get the following error message: Error in array(rfout$treemap, dim = c(2, nrnodes, ntree)) : dim<- length of dims do not match the length of object Higher values of nodesize also result in this error message but values of nodesize less than 5 do not. I'm using R-1.5.0 on a Linux box and I installed the randomForest package during the week 13 May 2002. Thanks in advance. mike -- ****************************************************************** | Michael Fugate Phone: (505) 667-0398 | | Los Alamos National Laboratory Fax: (505) 665-5220 | | Group: CCS-3, Mail Stop: B265 e-mail: fugate at lanl.gov | | Los Alamos, NM 87545 | ****************************************************************** -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
