Setting up KrigR
Installing KrigR
First of all, we need to install KrigR.
KrigR will not be submitted to CRAN to avoid the hassle of updating an already accepted package.
KrigR is only available through the associated GitHub repository.
A KrigR dependency, rgdal, is no longer available at CRAN. You need to download and install it separately as follows:
remotes::install_github("https://github.com/cran/rgdal")
I will work to remove this dependency as soon as possible and hope to achieve this (alongside additional KrigR development) in 2024.
Here, we use the devtools package within R to get access to the install_github() function. For this to run, we need to tell R to not stop the installation from GitHub as soon as a warning is produced. This would stop the installation process as early as one of the KrigR dependencies hits a warning as benign as Package XYZ was built under R Version X.X.X which can usually be ignored safely.
Subsequently, KrigR can be installed and loaded as follows:
Sys.setenv(R_REMOTES_NO_ERRORS_FROM_WARNINGS = "true")
devtools::install_github("https://github.com/ErikKusch/KrigR")
library(KrigR)
CDS API Access
Before you can access
Climate Data Store (CDS) products through KrigR, you need to open up an account at the CDS and
create an API key. Once you have created your account and registered for API credentials, you can always find them again on your personal page (which you access by clicking your name in the top-right corner of the webpage) on the CDS webpage:
Once you have done so, we recommend you register the user ID and API Key as characters as seen below (this will match the naming scheme in our workshop material):
API_User <- 12345
API_Key <- "YourApiKeyGoesHereAsACharacterString"
KrigR.
If this is your first contact with KrigR, we recommend strongly you follow the workshop material in order. If you return to KrigR with specific questions or ideas, we recommend you make use of the search function at the top left of this page. If you are short on time, the
quick start guide will be useful to you.
