Hi Mike,
Here is a more informative error from Stangling and sourcing the
vignette on the Windows builder:
...
reading in files with read_tsv
1 Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") :
cannot open file
'C:/Users/vobencha/Documents/R/win-library/3.4/tximportData/extdata/sailfish/ERR188297/aux/meta_info.
json': No such file or directory
...
The issue lies in readInfRepFish() at this line where file.exists() is
called:
auxPath <- file.path(fish_dir, aux_dir)
if (!file.exists(auxPath)) {
return(NULL)
}
'auxPath' is
"C:/Users/vobencha/Documents/R/win-library/3.4/tximportData/extdata/sailfish/ERR188297/aux"
which tests TRUE even though no such directory exists. I can reproduce
this weirdness with a simple example. No aux directory or aux file
exists in my home, yet it tests true when there is no trailing slash.
(The trailing slash is not valid in windows and therefore evaluates to
FALSE.)
file.exists("C:/Users/vobencha/aux")
] TRUE
file.exists("C:/Users/vobencha/aux/")
] FALSE
Believe it or not, you simply choose a bad directory name for Windows.
Section 1.1. 'Package Structure' of this link lists aux as a disallowed
file (directory) name:
https://cran.r-project.org/doc/manuals/r-devel/R-exts.html
You can reproduce this problem with any of the disallowed files names in
that section (disallowed because they are DOS device names). Examples
for the salmon files worked because you named the directory aux_info. If
you rename aux to something else (not listed in Section 1.1!) the
package should build successfully.
