search for: predplot

Venables and Ripley's MASS 3ed mentions a function predplot, used for plotting results of lda and qda. But even with the library MASS loaded, R (1.4.1) tells me predplot doesn't exist, and when I search the 1.4.1 documentation for predplot, it finds nothing. Does predplot still exist somewhere, or has it been replaced by a new and improved version wit...

I am trying to run, in R -Windows95, the example in MASS2, section 17.2. When I run predplot() on cush.lda I get > predplot(cush.lda, "LDA") Error: couldn't find function "max.col" I get the plot OK, but within predict(), it balks on max.col A more general question about using VR. Is there an easy way to use library on VR in general or do I have to move each...

Dear R Help Members, I am aware how to plot the LD1 vs LD2 from a lda in R, using the code: plot(baseline.systat.hat$x, col=baseline.systat.hat$class,pch=as.numeric(baseline.systat.hat$class)) However, I need to use the quadratic discriminant function, qda due to data properties. Is there a way to obtain the same sort of plot for from a qda object (and the output of predict qda). I have not

...ethod does (the default is to predict `NA'). - fitted() and residuals() now return NA for observations with missing values, if na.action is na.exclude. - `ncomp' is now reduced when it is too large for the requested cross-validation. - Line plot parameter arguments have been added to predplotXy(), so one can control the properties of the target line in predplot(). - MSEP(), RMSEP(), loadings(), loadingplot() and scoreplot() are now generic. See the file CHANGES in the sources for all changes. -- Ron Wehrens and Bj??rn-Helge Mevik _______________________________________________...
