reading from text file that have different rowlength and create a data frame
3 messages · Ram H. Sharma, jim holtman
?read.table Then look at the 'fill' & 'flush' parameters; this may do the trick

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

try this:

+ ; 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") + , comment = ';' + , fill = TRUE + , header = TRUE + , na.strings = '' + )
closeAllConnections() x
Var1 Var2 Var3 Var4 Var5 1 0 0.05 0.01 12 <NA> 2 1 0.04 0.06 18 A 3 2 0.05 0.08 14 <NA> 4 3 0.01 0.06 15 B 5 4 0.05 0.07 14 C
