[R] Line with linearly changing thickness – installation issues

[Ferri Leberl]

Dear All,
Thanks to Peter for his hint to the lwline package.
As a pitty, I have difficulties to get it installed, as it requires https://github.com/Gibbsdavidl/twine which failes for me.

install_github("git using github.com:Gibbsdavidl/twine.git")
 
ends with

** building package indices
Error in read.table(zfile, header = TRUE, as.is = FALSE) : 
  more columns than column names
ERROR: installing package indices failed
* removing ‘/usr/local/lib/R/site-library/twine’
Fehler in i.p(...) : 
  (konvertiert von Warnung) installation of package ‘/tmp/RtmpD3exKe/file730c303b4c3/twine_0.1.tar.gz’ had non-zero exit status

I found hints like
https://community.rstudio.com/t/lazydata-failed-for-for-package/4196 and
https://stat.ethz.ch/pipermail/r-help/2011-March/272829.html
that boil down to problems within the data subdir of the project – but I cannot (and should not) edit the project, can I?

Can anybody help me solving the problem?
Thank you in advance!
Yours, Ferri

Hmm... I don't recall whether this has been packaged up, but Paul Murrell talked about it at useR in Brisbane.
