I'm trying to create csv files out of an R table. But i cant understand why all the values get checked with "" when i use the write.csv() function. my data looks like this:
Sample Sample_Name Sample_Group Pool_ID Sample_Plate NorTum Sentrix_ID Sentrix_Position HybNR
1 00_11242 00_24200N2 MUTYH GS0005703-OPA GS0010004-DNA N 1280307 R007_C005 1
2 00_11242 00_24200N2 MUTYH GS0005704-OPA GS0010004-DNA N 1280307 R007_C011 1
3 00_11242 00_24200N2 MUTYH GS0005702-OPA GS0010004-DNA N 1416198 R007_C011 2
4 00_11242 00_24200N2 MUTYH GS0005701-OPA GS0010004-DNA N 1416198 R007_C005 2
5 00_7 00_7T MUTYH GS0005701-OPA GS0010004-DNA T 1416198 R006_C005 2
6 00_7 00_7T MUTYH GS0005702-OPA GS0010004-DNA T 1416198 R006_C011 2
7 00_7 00_7T MUTYH GS0005704-OPA GS0010004-DNA T 1280307 R006_C011 1
8 00_7 00_7T MUTYH GS0005703-OPA GS0010004-DNA T 1280307 R006_C005 1
9 01_677 01_677N HNPCC_UV GS0005701-OPA GS0010004-DNA N 1416198 R002_C006 2
10 01_677 01_677N HNPCC_UV GS0005704-OPA GS0010004-DNA N 1280307
And in the output file which is a CSV every value looks like this:
"100" "R05_80611" "R05_80611N" "NA_FAM" "GS0005701-OPA" "GS0010004-DNA" "N" 1416198 "R003_C006" 2
Why is the function putting quotes around my values and is there a way to quickly do this.
I'm also wondering how I can change my column names when writing to CSV files but since i`ma starter I've no clue on how to do this.
See manual write.table {utils} .
help(write.csv)
write.csv(X, quote = FALSE)
The justification for quoting the fields by default is that unquoted fields containing commas will be misinterpreted.
