[Bioc-devel] Windows Development Build Error Message for COHCAP

[Charles Warden]

Hi H,

Thank you for the additional information.

I have pushed the git updates using tempdir() instead of getwd().  It sounds like that will probably fix the problem, and I will check tomorrow.

Best Wishes,
Charles

FWIW here are 2 important reasons for writing temporary stuff to
tempdir() instead of the current working directory:

1. tempdir() is the only place that is guaranteed to be writable on every system. Yes the user home is very likely to be writable too but there is actually no guarantee and some systems have unconventional setups where it's not.

2. Whatever you put in tempdir() will automatically be removed at the end of the R session. Even though there are ways to achieve this with the temporary stuff you write in the user home, it's not automatic and hard to get right.

Cheers,
H.
