[R] reading from text file that have different rowlength and create a data frame
Hi R-experts
I have many text files to read and combined them into one into R that are
output from other programs. My textfile have unbalanced number of rows for
example:
;this is example
; r help
Var1 Var2 Var3 Var4 Var5
0 0.05 0.01 12
1 0.04 0.06 18 A
2 0.05 0.08 14
3 0.01 0.06 15 B
4 0.05 0.07 14 C
and so on
Inames<-as.data.frame(read.table("CLG1mpd.asc",header=T,comment=";"))
Inames<-as.matrix(read.table("example.txt",header=T,comment=";"))
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,
:
line 1 did not have 5 elements
In bestcase scenerio, I want to fill the blank space with NA's, with matrix
or dataframe
Var1 Var2 Var3 Var4 Var5
0 0.05 0.01 12 NA
1 0.04 0.06 18 A
2 0.05 0.08 14 NA
3 0.01 0.06 15 B
4 0.05 0.07 14 C
The minimum would be to remove the column Var5, so that my data.frame would
look like the follows:
Var1 Var2 Var3 Var4
0 0.05 0.01 12
1 0.04 0.06 18
2 0.05 0.08 14
3 0.01 0.06 15
4 0.05 0.07 14

Thank you in advance for the help.

[R] reading from text file that have different rowlength and create a data frame
?read.table Then look at the 'fill' & 'flush' parameters; this may do the trick On Mon, Apr 4, 2011 at 9:32 AM, Ram H.
