Error in writeLines

[chuddy-ibk]

Hi folks

I tried to use the R version of webgestalt.
Unfortunately, it takes much more time to get things started than expected. I already tried everything in the browser and it worked fine.
In R, however, I go from one error to the next. I think I am close to getting through completely.
The interestGeneFile is the same I used online where it worked.
Using the test interestingGenes.txt from webgestalt works perfectly as well. When I truncate my txt file and delete many of the gene symbols, I won't get an error but I wont get all the files in the result folder, i.e. the html file is missing and something else as well.
Normally, I would want to use mmusculus, but for establishing, capitalized as gene symbols. In any case, also when i go for mmusculus and won't change anything in the gene list (only first letter capitalized), I get the same error (see below)

filt_LFC-1_p0.05.txt

Input:
outputDirectory <- getwd()
enrichResult <- WebGestaltR(
enrichMethod = "ORA", organism = "hsapiens",
enrichDatabase = "geneontology_Biological_Process",
interestGeneFile = "filt_LFC-1_p0.05.txt",
interestGeneType = "genesymbol",
referenceSet = "genome",
referenceGeneType = "genesymbol",
isOutput = TRUE,
outputDirectory = outputDirectory,
projectName = NULL
)

Output:

Sorry for the delayed response.

This seems to be an error in the kMedoid clustering. if you add usekMedoid = FALSE as a parameter to the WebGestaltR function call, you should avoid this for now. I will work on a fix so this won't be necessary, but that should be a temporary solution.
