geolink_population()

[dasalm20]

Dear @DianaJaganjac,

I have tested the population function and it is currently failing. These are my findings:

1. The name set is not being created properly. In lines 587 it is expecting a start and end year, but we do not pass on those arguments to the function. Thus, the name_set is null

I think that once it is created properly, the function should run without any issues.

This is the code that I am using:

test_dt <- geolink_population(iso_code = "NGA", UN_adjst = "N", constrained = "Y", shp_dt = shp_dt[shp_dt$ADM1_EN == "Abia",], grid_size = 1000, extract_fun = "mean", file_location = "/Users/nikos/Documents/temp")

@DianaJaganjac ,

I tested the latest function for population and I get the following error:

test_dt <- geolink_population(iso_code = "NGA", UN_adjst = "N", constrained = "Y", shp_dt = shp_dt[shp_dt$ADM1_EN == "Abia",], grid_size = 1000, extract_fun = "mean", file_location = "/Users/nikos/Documents/temp") trying URL 'https://data.worldpop.org/GIS/Population/Global_2000_2020_Constrained/2020/maxar_v1/NGA/nga_ppp_2020_constrained.tif' Content type 'image/tiff' length 52433902 bytes (50.0 MB)

Hi Daylan,

I just used this example and it worked for me:

Example usage

df <- geolink_population(iso_code = "NGA", UN_adjst = "N", constrained = "Y", shp_dt = shp_dt[shp_dt$ADM1_EN == "Abia",], grid_size = 1000, extract_fun = "mean", file_location = "C:/Users/Diana Jaganjac/Documents/New folder")

Please try again and let me know if it works for you.

You might need to double check your file location where you are downloading the data to.

Best wishes,

Diana

Hi Diana,

You are right, I think the issue was with the file_location. I will further test it and let you know.

Best, Daylan
