I work with Windows, R version 2.4.1 I am trying to plot the results of a discriminant analysis done using the lda function in the MASS library. The discriminant. analysis goes like this:
data.tb<-read.table('C:\\Documents and Settings\\silvia\\Desktop\\dicrim_test.txt', header=T) ## the actual made-up test matrix is pasted below train<-sample (1:36, 15) table (data.tb$group[train]) data.lda<-lda(group~., data.tb, subset = train) predict (data.lda, data.tb[-train,])$class Then I want to obtain a plot by writing: >plot(data.lda, cex=0.7, 2, xlab='LD1', ylab='LD2') but it's not working. It says that it could not find the function panel. When I include panel=panel.lda, it tells me that the object 'panel.lda' was not found. All I get is an empty plot in the graphics window. Was I supposed to create an object called panel.lda? I cannot find in the help what that object might be. Any help would be appreciated.
