[R-pkg-devel] Saving output of check()

In trying to test that an upgrade to my optimx package does not break other
packages, I wanted to loop over a list of all such packages in alldep, with
nall the length of this list.

cat("Check the dependent packages\n")
for (ii in 1:nall){
  cpkg <- alldep[ii]
  dd <- "/home/john/temp/wrkopt/dlpkg"
  dlname <- download.packages(cpkg, destdir=dd )[[2]]
  cat("Downloaded ", dlname,"\n")
  cpkg.chk <- devtools::check_built(dlname)
  cat("Results package:",cpkg,"\n")

Before running this, I did

sink("dpkgcheck.txt", split=TRUE)

and afterwards, I did sink().

But ... none of the check output, nor the result of the final print, show
up in the output file dpkgcheck.txt.

Have I totally misunderstood sink(), or is there a nasty bug?

I've tried running in Rstudio and in the terminal. I'm running Linux Mint
18.3 Sylvia.
