set download directory

[ktoddbrown]

Hi I was wondering if there was a way to set the download directory without reseting the environmental variables?

Thanks for this. Are you talking about a specific function?

[ktoddbrown]

Sorry! I'm looking to download pangaea data to a specified local directory and then load the data into R and be able to work with it offline. I'm running the below function (and data set):

data.df <- pangaear::pg_data(doi = '10.1594/PANGAEA.863689')

[sckott]

@ktoddbrown what "environmental variables" are you talking about?

[sckott]

we store the base path to save files to in env$path, so in theory you could change that path, but it's not exported to the user right now. i can see about letting the user set the working directory

[ktoddbrown]

Yep, this is what I was interested in.

[sckott]

can you reinstall remotes::install_github("ropensci/pangaear@cache-path"), restart R session, and try again. See pg_cache$cache_path_set() to set the cache path

[sckott]

changes in caa3cb3

[ktoddbrown]

This is not quite what I was looking for. I would like to download the files to a specified directory. For example right now

> pg_cache$cache_path_set('/Users/name/Documents/Datasets')
[1] "/Users/name/Library/Caches/R//Users/name/Documents/Datasets"
> pg_cache$cache_path_get()
[1] "/Users/name/Library/Caches/R//Users/name/Documents/Datasets"

but I would like to point the director to: the folder "/Users/name/Documents/Datasets"

[sckott]

I've been planning to make it easier to set the path directly ropensci/hoardr#12 but not done yet. for now try this:

x = pg_cache
x
#> <hoard>
#>   path: pangaear
#>   cache path: /Users/sckott/Library/Caches/R/pangaear
iset_the_path <- function(path) x$.__enclos_env__$private$hoard_env$cache_path <- path
iset_the_path("/Users/name/Documents/Datasets")
x
#> <hoard>
#>   path: pangaear
#>   cache path: /Users/name/Documents/Datasets

[sckott]

@ktoddbrown sorry for the very long wait on this - done now - can install from github master branch. just set your own path with pg_cache$cache_path_set(full_path = "/Foo/Bar")
