Yes I found the same error in my windows virtual machine test. I added a dependency package crayon to print console message with color, which need to be installed from github instead CRAN. I have fixed run.R script to make sure this, your test was before that fix.

You can try the newest version, it should be fixed.

Sadly, windows console doesn't support ANSI color so you will not see them in color, unless you are using conemu or cmder.

Oops. My mistake. Thanks. I had loaded all the packages on my development machine, and was running the app directly without sourcing run.R. It works fine when I source run.R.

As a side node, r-lib/crayon on CRAN is not available for R3.4.1, so you need to install from github as done in run.R.

> install.packages('r-lib/crayon')
:
2. package ‘r-lib/crayon’ is not available (for R version 3.4.1)

Yes, run.R install crayon from github (the older version didn't recognize number input, that's why you are getting that error). So even if you are running locally, it's suggested to run run.R at least once to install the dependency packages first.

Ideally I can put some code in the app so it will try to install from github for these special packages. However installing lots of packages in one run often met problems, and I found it's easier to install github packages separately, since the CRAN packages usually are tested more frequently and cause less problems in installation.

I just found that the newest RStudio preview version in windows should support ANSI color in console. I haven't verify in my windows VM yet, but I guess the color message should work if you install the newest version.

Good to know, thanks. I do most of my work on a Mac, and the color looks good there.
