Datasets not exported/available from my R package

Following advice about NAMESPACE and External Data formatting/setup, I have:

A. My data files in mypackage/data/datafilename.RData

folder list of data files

B. The data script as mypackage/R/data.R with data files individually named and described within that one file, having just changed "itemize" to "describe" and changing the format of those item lines:

C. I've document()-ed this, commit-pushed to github, and install_github reinstalled locally.

Help for the data files works:

But I can't access those data, whereas I can access data in other packages using the same method:

data load fail

Can anyone think why this would be? NAMESPACE doesn't include these as exports:

namespace

But it's autogenerated by document() so that's arguably out of my control. By comparison, mapplots' NAMESPACE has exportPattern(".")

Environment for the package also doesn't include them, but I don't know if this is expected or not, based on lazy loading (which is true):

Any ideas welcome. I've tried data(gbm.auto:grids) with 1, 2 & 3 colons, to no avail. Based on the answer to this related question (also by me), I get the suspicion that there might be some issue whereby only the last named object in data.R is important/accessible?

usethis has been created since I've been updating this package and has use_data and create_package but I'm reluctant to try these out since ostensibly everything in my package should already be in order and I don't want to make things worse.

Thanks in advance. Reprex would be

library(devtools)
install_github("SimonDedman/gbm.auto")

Edit: to add to this, the datasets available in the installed package are a combo of the full list, some individual, some named in datalist:

datalist

Which contrasts against what's in the working folder and github:

github data folder

As far as I can see, all the data files are the same format, e.g. when doubleclicked in file explorer they open in RStudio with the right name and same format. gbm.auto/R/data.R file is here. Per the last image, the three data files listed in datalist can be loaded in R with library(gbm.auto) data(Juveniles), but the other three data files can't. If I delete/rename the existing datalist from /data and generate a new one with add_datalist(pkgname = getwd()), a new file is generated but again it only lists those 3 files, not all 6.

Ugh, goddamn it. Found the issue. The 3 'bad' files had "Rdata" extensions while the 3 good ones had "RData" extensions. Lower case vs capital D. How unbelievably annoying.

Solution

  • Data files in data must have .RData extensions, not .Rdata
