I'm having trouble getting the gbm package to load on my new 64 bit machine
running xp professional OS. I installed version 2.72 and loaded the
package, although I got an error message:
The downloaded packages are in
C:\Documents and Settings\Administrator\Local
Settings\Temp\RtmpQbYngm\downloaded_packages
updating HTML package descriptions
> fin<-read.csv(c:/documents and settings/administrator/my
> documents/R/fin_sb_mat.csv")
Error: unexpected '/' in "fin<-read.csv(c:/"
> fin<-read.csv("c:/documents and settings/administrator/my
> documents/R/fin_sb_mat.csv")
> fin.tc5.lr01 <- gbm.step(data=fin,
+
+ gbm.x = 7:14,
+
+ gbm.y = 24,
+
+ family = "bernoulli",
+
+ tree.complexity = 5,
+
+ learning.rate = 0.01,
+
+ bag.fraction = 0.5)
Error: could not find function "gbm.step"
Any ideas on what could be wrong?
John
