error in cache directory/file

[sgsalmo]

Hi Hugh,

I tried to follow your code posted in twitter. But then, I got an error message, as:

I am not sure what gives the error. Hope you can help me again. I am using Macbook Pro (on Mac OS Big Sur), on RStudio 1.4.1103.

One of your suggestions is to make a "file path". Sorry, Im not that familiar with this. Hope you can help clarify.

Thanks,

SS

Here is the function with an example of how to specify and create the full file path:

#define full directory path
my_cache <-  '/home/sgsalmo/rayvistaproject/cache'

#check if directory exists - if not then this creates a new directory
if (!file.exists(my_cache)){
    dir.create(my_cache)
}

plot_mountain <- function(.coord, .name, .filt){
  next3d()
  mountain <- plot_3d_vista(lat=.coord[1], long=.coord[2], radius = 7500,
                            zscale=3, elevation_detail = 14, overlay_detail= 14,
                            outlier_filter = .filt ,zoom=0.8,
                            theta=sample(-175:-1, 1), windowsize =c(800,1200),
                            phi=15, solid=F, cache_dir =my_cache)
  render_label(heightmap= mountain, text=.name, lat = .coord[1],
               long=.coord[2], extent = attr(mountain, 'extent'), relativez=T,
               zscale=3, z=1000, alpha=0, family='mono')
}

Thanks, Hugh! It is now working.

Great, thanks for letting me know!
