[R] Sourcing my file does not print command outputs

I looked at the documentation of source() and summary(), and I could not
find the reason why calling something like:
> summary(resamps)
from the command line, works (it prints the summary)

whereas calling

summary(resampls)

from a file that I source with source("my_file.r") does not print
anything.

How can I get summary(resamps) to print when I source a file with this
command?

Thanks,

James

[R] Sourcing my file does not print command outputs

From ?source
"Note that running code via source differs in a few respects from entering
it at the R command line. Since expressions are not executed at the top level,
auto-printing is not done. So you will need to include explicit print calls for
things you want to be printed"

James,

You might also want to look at ?source for the echo or print.eval parameters to
the source() function.  Using

    source("my_file.r", echo=TRUE)

or

    source("my_file.r", print.eval=TRUE)

may get you what you want without adding explicit print statements to your
script file.


Hope this is helpful,

[R] Fwd: Sourcing my file does not print command outputs

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

[R] Sourcing my file does not print command outputs

Thanks Dan. The ... is an accidental typo in the email. Would you mind
verifying that dotplot opens a plot  *without* print.eval=TRUE?

Thanks,

J.
