Obtain all attributes from an rgbif occurrence download

I have downloaded occurrence data using the rgbif package successfully. However, the attributes that are available seem restricted. Specifically, I would like: Habitat, Identification remarks and Occurrence remarks. Is there a way to obtain that information via R?

library(rgbif)
# Request data 
occ_download(pred_and(pred("phylumKey", 35), pred("gadm","ETH")),
             format = "SIMPLE_CSV")

# Check download status using occurrence number,
# see result in console from previous step
occ_download_wait("download occurrence number")

# Load data
df <- occ_download_get("download occurrence number") %>%
  occ_download_import()

Explore data : no attributes for habitat, etc

names(df)

Solution

Thanks to the comment by @Grzegorz Sapijaszko I was able to resolve the issue. I had requested SIMPLE_CSV as the file format for download (as in many of the tutorials I had followed). However, the number of attributes available from a SIMPLE_CSV is limited. To get all available data, use DWCA as a method of download. This downloads data into multiple separate text files into a folder. Here is the updated code (also a simple tweak to make it more easily reproducible by saving the download number into a res object and changed the phylum to one with fewer species to speed up the example).

library(rgbif)
# Request data 
res<-occ_download(pred_and(pred("phylumKey", 13), pred("gadm","ETH")),
             format = "DWCA")#!!!! change SIMPLE_CSV to DWCA

# Check download status using occurrence number,
# see result in console from previous step
occ_download_wait(res)

# Load data
df <- occ_download_get(res) %>%
  occ_download_import()
