Thank you! I have been thinking of using length but it would make the
test more complex. I did not know about all() but it looks like the
tool for the job. Cheers

When I do full CRAN/BIOC installs I use Xvfb via something like
Xvfb :5 -screen 0 1280x1024x24 &
setenv DISPLAY :5

You can define the environment variable R_DONT_USE_TK (to any value) to
avoid this hang caused by code in the tkrplot package. You do not have to
have an X server running if R_DONT_USE_TK is set. This will avoid
potential hangs while installing the 23 packages that depend on tkrplot.

I tried this a second time, but with --no-byte-compile, and it hung with a
slightly different traceback

Bill-- BINGO.You have found the answer. After some testing on one of
my environments where it was always hanging, connecting to the same server with
an X-Sever running on my workstation did indeed allow the package to be
installed.

This is a microcosm of why installing "all CRAN" packages is a bad idea. Now
extend this to the other 5% of 16000+ packages that will have unclear
requirements, and when you have all those installed try to update just one of
the packages because one of your users has learned of a bug in that pac
Alternatively you can modify the test as follows:
length(unique(df_b$q)) == 1

[1] FALSE
If this isn't it, just ignore without reply.

No it shouldn't work. unique returns zero or more results so == with a constant
will be a logical vector zero or more elements long, which is inappropriate for
&&. Use the any function perhaps.

I just tried installing forensim on R-devel/Ubuntu 20.04/WSL-2.0 without an
X server (hence DISPLAY was not set). Loading tktcl gives a warning that
Tk is not available because DISPLAY is not set. The installation hung
after the byte-compile message:
installing to
/home/bill/R-devel/R-build/site-
(As I said, I'll try anything!)
OK, so I went ahead to get the scl devtoolset, and rebuilt R 4.1.1 with the
same exact gcc you used.
But- same result for me. Hung at the byte-compile step when installing that
one package, no error, no messages, no logs.

Yes, but the && should work within `unique(df_b$q) == ""` because the
test should be: (IF THE DATAFRAME HAS ZERO ROW) OR (ALL THE ELEMENTS
OF $q ARE EMPTY) THEN (PRINT empty).
Can I collapse the TRUE FALSE of `unique(df_b$q) == ""`into a single FALSE?

Hi,
The OR operator you used is working as expected: || starts from the
left and evaluates only enough of the options to determine the
results. The first test is TRUE, so the result is TRUE. It sounds
like you might actually want an AND operator, & or &&, which will only
return TRUE if all elemen
Hello,
I have two data frames, each with three rows:
```
df_a <- data.frame(a = letters[1:3], b = LETTERS[1:3], q = c("", "", ""),
stringsAsFactors = FALSE)
df_b <- data.frame(a = letters[4:6], b = LETTERS[4:6], q = c("", "", "1.5"),
stringsAsFactors = FALSE)
```
I need to test whether the datafram
14 matches
