error_message M-LED process_clusters.R

[beniaminogallizia]

Hi,
I'm working on a new country, Mozambique. I'm aving this error message while running process_cluster.R. In particular the run stopped at line 79. I already checked the version for R and Rstudio.

Error in (function (cond) :
error in evaluating the argument 'x' in selecting a method for function 'raster': subscript out of bounds

This is the clusters' matrix.

Do you have any suggestions?

Thank you in advance.

Dear @beniaminogallizia, great that you are looking into an implementation of M-LED for Mozambique.

The reason is most likely that you did no download the nighttime light dataset that is being read in line 79.

The data file in question is referred to here: https://github.com/iiasa/RE4AFAGRI_platform/wiki/Examples-and-exercises#preparing-the-population-clusters-also-relevant-for-onsset and can be downloaded from here: https://eogdata.mines.edu/nighttime_light/annual/v21/2021/VNL_v21_npp_2021_global_vcmslcfg_c202205302300.median_masked.dat.tif.gz.

Could you confirm if you downloaded it and unzipped it?

[beniaminogallizia]

It works! I was using the nighttime light file specific for Mozambique that i used for OnSSET, apparently it was not suitable.

Thank you again!

Great! Please keep us posted on your model development outcomes, if you wish :)

Hi giacomo, i'm encountering another issue.
I'm trying to manually installing some packages from gz files where the code give me errors installing from sources.

Do you have any suggestions?

[giacfalk]

Dear @beniaminogallizia, what version of R are you using?

[beniaminogallizia]

I'm using the following version: R-4.2.3. As suggested in one of the previous issue I didn't downgrade Rstudio.

[giacfalk]

did you try to add the dependencies=T argument in the install call? Otherwise, I did not get why you are instlaling manually some packages. Don't they install via CRAN?

[beniaminogallizia]

It showed me the message below so I look for other versions in the web (https://cran.r-project.org/src/contrib/Archive/randomForestSRC/).

I didn't try too add dependencies=T, i'll try it.

Thank you

Hi Giacomo,
i'm having this error message that i'm not able to solve:

this error is related to an if sentence introduced in the electricity_access.R file:

!is.na(unique(values(resources))) should gives just one boolean value but it returns a boolean vector. I don't know how to proceed.
Can you help me understand how to interpret this part of the model?
Thank you

[giacfalk]

Hi @beniaminogallizia ,

Can you post the console output of running unique(values(resources)) ?

Thanks

[beniaminogallizia]

[giacfalk]

I think there is an issue with the object resources.

Could you please run lines 60-75 of the electricity_access.R file

RE4AFAGRI_platform/mled/electricity_access.R

Line 60 in 26f347d

prio <- read.csv(find_it("PRIO-GRID Static Variables - 2021-05-24.csv"))

and then post the console output of the resources object?

[beniaminogallizia]

Good afternoon Giacomo,

I change the machine in order to have a larger CPU, now i'm using the work station of my institution. I'm facing the same problem.
This is the result from summary(resources):
layer
Min. 1
1st Qu. 1
Median 1
3rd Qu. 1
Max. 1
NA's 2507889
while this is the output for View(resources):

Do you have any suggestions on how to solve the issue?

Thank you in advance for the patience.

Beniamino
