install.packages('rerddap') fails on Windows

[mwengren]

I'm an R newbie, but I can't install rerddap on Windows without the following error.

Am I missing a step, or is it not compatible with my environment?

Windows 10 R 3.2.5 (64 bit)

> install.packages("rerddap")

  There is a binary version available but the source version is later:
        binary source needs_compilation
rerddap  0.3.4  0.4.2             FALSE

thanks for the issue @mwengren - on vacation this week, will answer next week

@mwengren The bit to pay attention there is there is no package called 'DBI'

try install.packages("DBI"), then try installing rerddap again

[mwengren]

Thanks, that did the trick. Not knowing much about R, I assumed it would do some dependency management to install dependent packages. Recommend adding the dependencies directly to your readme.md

install.packages("DBI")
install.packages("rerddap")

so users who expect to follow those and have it work won't be stumped.

@mwengren glad it worked. that's a bit odd you had that problem since I think DBI is needed via dplyr, but dplyr has DBI in Suggests, so i don't think DBI is needed when installing this pkg.

I'm on R v.3.4.1

I thought I might be able to replicate your problem on my Mac with R 3.2.5 but i couldn't replicate the problem, installation went fine.

I can certainly add a note to the readme in case users see the same problem
