getCHIRPS- Error in serverPath() : could not find function "serverPath"

[machaielder]

As I could not download the HeavyRain Master from the Rstudio command line I downloaded it manually and run the following to download CHIRPS rainfall data:

chirps_africa<-getCHIRPS(region = "africa", format = "netcdf", tres = "monthly", sres = 0.05, dsn = file.path(getwd(), "data"), overwrite = FALSE, cores = 2)

The Rstudio brought the following error message: Error in serverPath() : could not find function "serverPath" Can You help me with this issue? Is there any specific thing I should I have done in order to path all necessary packages at the same time? Thanks in advance

African monthly images are not provided in NetCDF format, see #2. Using format = "tifs" should solve your issue:

chirps_africa <- getCHIRPS(region = "africa", format = "tifs"
                           , tres = "monthly", sres = 0.05
                           , dsn = file.path(getwd(), "data"), cores = 2)

Thank you very much for your help. However, it still gives the same error message. Error in serverPath() : could not find function "serverPath" Thank you.

[fdetsch]

Hm, I fail to reproduce the described behavior. Can you please provide your sessionInfo()?

[machaielder]

[fdetsch]

Thanks. Can you please load heavyRain and create the sessionInfo() afterwards? In addition, what happens if you run heavyRain:::serverPath() in the console?

[machaielder]

Thank You! I get the following error message: Error in loadNamespace(name) : there is no package called ‘heavyRain’

Does this error have anything to do with the fact that I downloaded the heaveyReain manually to run in Rstudio? Thank You in advance.

[fdetsch]

That might well be. Could you please do the following

remotes::install_github("environmentalinformatics-marburg/heavyRain")

and test with this version again in order to verify that?

[machaielder]

It did not work again. I had tried it before and got error

devtools::install_github("environmentalinformatics-marburg/heavyRain") Downloading GitHub repo environmentalinformatics-marburg/heavyRain@master Error in utils::download.file(url, path, method = download_method(), quiet = quiet, : cannot open URL 'https://api.github.com/repos/environmentalinformatics-marburg/heavyRain/tarball/master'

[fdetsch]

Can you download the tarball (simply click the link above) and install the package from the .tar.gz file manually? If not, I fear there might be something wrong with your internet connection (firewall/VPN issue, etc.).

[machaielder]

I downloaded it manually and run. I got the same error message. Error in serverPath() : could not find function "serverPath"

[fdetsch]

Again, please include your sessionInfo() created right after running library(heavyRain). In addition, does heavyRain:::serverPath() still fail?

[machaielder]

library(heavyRain) Error in library(heavyRain) : there is no package called ‘heavyRain’

[fdetsch]

You have to find a way to install the package first. This is no issue related to the package, but rather to your software/network setup, which is why I am closing this thread now.

Try to install the package either using remotes::install_github() or from a local resource (ie. a .tar.gz file). Afterwards, you'll be able to run library(heavyRain) and use its functionality.

[tim-salabim]

@machaielder you can try this solution using devtools::install_local('path/to/your/downloaded/heavyRain-master.zip')

[machaielder]

Thank you very much. The error stills remains. I can't figure out whats happening. llibrary("devtools")

[tim-salabim]

I think you first need to install.packages(c("gdalUtils", "gimms", "ncdf4", "R.utils", "raster", "RCurl")) and then run devtools::install_local('heavyRain-master.zip')

[machaielder]

I did not install. Does it have to do with rhe r version?

[tim-salabim]

Seems to me like you either have no internet connection or sit behind a firewall that disallows R to install things.
