Hi everyone,
I have a matrix with multiple columns like this:
charge convexhull_xCoor id
3 3336.43 f_7936733956214261295
3 3339.73 f_7936733956214261295
3 3336.43 f_7936733956214261295
2 3797.14 f_2444900193131259878
2 3799.41 f_2444900193131259878
2 3800.93 f_2444900193131259878
I want to get only one row per uniq id, removing the rest of the rows
(it doesn't matter which of the rows with the uniq id is kept). In R
this is equal to:
> csv <- read.csv('/homes/ndeklein/infiles/feature.csv', head=TRUE,
sep='\t')
> csvUniq <- subset(csv, !duplicated(csv$id))
So using rpy2 this would be
csvData = R.r['read.csv'](file=inputFolder+'feature.csv',
head=True, sep='\t')
csvUniqID = R.r['subset'](csvData,
R.r['duplicated'](csvData[R_funct.index(csvData, 'id')]))
Except that I don't have !duplicated but duplicated.
R.r['!duplicated'] is not recognized and doing
It is not recognised because there no symbol "!duplicated".
R.r.__getitem__() is fetching objects associated with symbols, it is not
evaluating R code.
rnot = R.r['!']
duplicated = R.r['duplicated']
rnot(duplicated(foo)) is now equivalent to "!duplicated(foo)"
csvUniqID = R.r['subset'](csvData, not
R.r['duplicated'](csvData[R_funct.index(csvData, 'id')]))
Also doesn't work (it seems to ignore the not). So how do I get the !
infront of duplicated?
Thanks,
Niek
