Re: [R-pkg-devel] sf subsetting with square bracket

Hi,

if sf is not loaded, subsetting an sf object with square brackets loses the sf 
class in the geometry column:
sfobj[somerows,]
For usage in a package, I do not want to call library(sf) first.

[ is an S3 method in sf:
https://github.com/r-spatial/sf/blob/master/NAMESPACE#L6
https://github.com/r-spatial/sf/blob/master/R/sf.R#L299

In my package (with an sf object from osmplotr), using
sf:::"[.sf"(obj, somerows, allcolumns)
works fine, but of course Rcmd check complains about the Unexported object 
imported by a ':::' call.

How can I use the sf [ method without completely loading sf?
(and also without depending on dplyr::select)

I guess I'm missing some really clever method import.
Can someone point me in the right direction?


You need to show us something reproducible if you want help.  Is your 
package on Github or some other public repository?

Re: [R-pkg-devel] Problem installing built vignettes

[Alexandre Courtiol]

Hi Chris,
I solved the issue directly in the code after forking your repos and send
you a pull request.
The folder vignette was at the wrong place and I added the .asis files as
well as updated the description file.
I hope it will work on your system.
