I want to use debroswer to analysis my RNAseq data, when I upload csv files it always shows "Warning: Error in writeImpl: Text to be written must be a length-one character vector", anyone know what the warning means?
I am having the same issue. I can upload my counts data file, but when I try to upload the metadata with it, the app exits with the same warning. Did you have any luck? Thanks!
same issue...any solution
For others to help, you need to provide the output of the
sessionInfo()command. You need to make a simple reproducible example (R code that someone else can cut-and-paste into their R session, so it can't use data only available to you), for instance using the data used by the vignette of the package (browseVignettes(package="DEBrowser")).I fixed my issue. Apparently you can't use column names in R starting with numbers. They need to start with letters. Also, I created my metadata file in Mac. When I opened it on a PC, it had extra blank row in between sample rows. Looks like Windows put an extra return at the end of the line. Changed both of these and now it runs fine.
Hope this helps!

I had the same issue. Apparently, it mainly has to do with column (sample) names as already suggested. I discovered that after I removed dashes (-) from my column names, it works.
I had named my samples according to their authors and one of them had a compound name. So initially those sample names looked something like abc_rep1_John-Doe. Renaming it to abc_rep1_JohnDoe solved the problem for me and I was able to upload successfully.
I hope this helps someone.
