Hello. I'm a student who just start learning the Rstudio.
However, I have a problem.
While solving my homework in my Rstudio Cloud,
I continuously get that error message:
'The previous R session was abnormally terminated due to an unexpected crash. You may have lost workspace data as a result of this crash.'
and with this message, all of my variables which saved in my environment are deleted.
The codes I run is like this:
cols = c('chrom', 'source', 'feature_type', 'start', 'end', 'score', 'strand', 'phase', 'info')
d = read_delim('gencode.v31.basic.annotation.gtf.gz', delim='\t', skip = 5, progress = F, col_names = cols)
d1 <- d %>% group_by(source)
d2 <- d %>% group_by(source,chrom)
Because I am a beginner, my knowledge is short but please help me..
