QUESTION
I'm building a package that imports {sf}
, and more specifically I use st_length()
in one of my functions.
I initially added only {sf}
to my package "Imports", but when I checked it I got a few {lwgeom}
related errors:
ANSWER

package in Suggests field of your package DESCRIPTION file. It should do the trick.
QUESTION
I know the function has an quiet
argument, but I'm trying to suppress the message when quiet = FALSE
.
This may be weird, but I came across this issue when testing a package I'm writing. I'm using testthat::expect_message()
when setting quiet = FALSE
, but the function is not actually suppressing the message (it should, and in fact it usually does with "normal" messages).
I tried it with suppressMessages()
, but it didn't work as expected:

doesn't work because the progress text isn't an R message()
, it's the stdout of the the system library that download.file()
delegates the actual downloading to (e.g. libcurl
, wget
or wininet
). quiet = TRUE
bypasses this by setting the appropriate command line option of that tool.
You can divert stdout from the R console to a file with sink()
. Since you don't need it, you can use nullfile()
to open a file connection to the platform-dependent null device:

Install gtfstools
You can use gtfstools like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
