Thanks Dan,
Here is a minimal full example, where dotplot fails to print anything if I
source the file. I have tried restarting R and directly sourcing this file
without doing anything else first (my .Rprofile is empty). This is running
on Linux with the latest stable version of R.
========================================
#Setup
rm(list = ls(all = TRUE))
set.seed(1)
#Generate an input matrix with 10,000 values
#2,000 rows, 5 columns
X <- data.frame(replicate(5, rnorm(2000)))
#Construct Y using X
Y <- runif(1)*X[,1]*X[,2]^2+runif(1)*X[,3]/X[,4]
#Convert Y to binary
Y <- as.factor(ifelse(sign(Y)>0,'X1','X0'))
#Create bootstrap samples for fitting models
library(caret)
print("Creating bootstrap samples")
tmp <- createResample(Y,times = 25)
myCtrl <- trainControl(method = "boot", index = tmp, timingSamps = 10)
RFmodel <- train(X,Y,method='rf',trControl=myCtrl,tuneLength=1)
NNmodel <- train(X,Y,method='nnet',trControl=myCtrl,tuneLength=3, trace =
FALSE)
## GLMnet = GLMmodel,
...
#Assess re-sampled (out of sample) accuracy
print("Assessing re-sampled (OOB) accuracy")
resamps <- resamples(
list( RF = RFmodel,
NN = NNmodel
))
print("Summarizing resamps")
summary(resamps)
dotplot(resamps, metric = "Accuracy")
========================================
Thanks,
James
