TST: Creating vignettes fails on Travis CI repeatedly #72

Closed sinhrks closed 8 years ago

sinhrks commented 8 years ago

From yesterday, following error occurs on Travis CI repeatedly. Maybe any dependencies has been changed? Strangely I can't reproduce the issue on my local.

The branch is unmodified fork of current master:

* creating vignettes ... ERROR
Loading required package: proto
Loading required package: ggplot2
Warning in rgl.init(initValue, onlyNULL) :
  RGL: unable to open X11 display

The error message says it is related to lfda block.

library(lfda)

# Local Fisher Discriminant Analysis (LFDA)
model <- lfda(iris[-5], iris[, 5], 4, metric="plain")
autoplot(model, data = iris, frame = TRUE, frame.colour = 'Species')

model <- klfda(kmatrixGauss(iris[-5]), iris[, 5], 4, metric="plain")
autoplot(model, data = iris, frame = TRUE, frame.colour = 'Species')

@terrytangyuan Any thoughts? Either results can be complex number logically...?

This is very strange. I believe something might have changes rgl package, which tries to open the x11 device. Nothing has been changed for lfda package. I haven't looked into the PR yet but it seems like that the failure only happens when you merge PR even when it's passed during the PR.

If the tests and vignettes run fine locally, let's just skip the vignettes building during Travis for now. Try something like:

r_build_args: --no-build-vignettes --no-manual --no-resave-data
r_check_args: --no-build-vignettes --no-manual

Thanks, I temporary removed it by changing extension (as other vignettes work).
