Hi,
I guess you should have "fill=TRUE" in the read.table.
dat1<-read.table(text="
First line: Skip this line
Second line: skip this line
Third line: skip this line
variable1 Variable2 Variable3 Variable4
Unit1 Unit2 Unit3
10 0.1 0.01 0.001
20 0.2 0.02 0.002
30 0.3 0.03 0.003
40 0.4 0.04 0.004
",sep="",skip=4, fill=TRUE,header=TRUE)
dat1<-dat1[-1,]
row.names(dat1)<-1:nrow(dat1)
dat1
variable1 Variable2 Variable3 Variable4
1 10 0.1 0.01 0.001
2 20 0.2 0.02 0.002
3 30 0.3 0.03 0.003
4 40 0.4 0.04 0.004

Subject: [R] Skipping lines and incomplete rows
I have a text file that has semi-colon separated values. The table is nearly
10,000 by 585. The files looks as follows:
*******************************************
First line: Skip this line
Second line: skip this line
Third line: skip this line
variable1 Variable2 Variable3 Variable4
Unit1 Unit2 Unit3
10 0.1 0.01 0.001
20 0.2 0.02 0.002
30 0.3 0.03 0.003
40 0.4 0.04 0.004
*******************************************
The first three lines need to be skipped. Moreover, line 5 doesn't have
units for all the variables and hence, has to be skipped as well.
Effectively, I want the following to be read to a dataframe skipping rows 1,
2, 3 and 5.
*******************************************
variable1 Variable2 Variable3 Variable4
10 0.1 0.01 0.001
20 0.2 0.02 0.002
30 0.3 0.03 0.003
40 0.4 0.04 0.004
*******************************************
I tried using read.table with skip for line 1-3 as follows
inputData <- read.table("test.txt",sep = ";",skip = 3)
but the line 4 is creating problem with the following error:
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,
:
line 3 did not have 585 elements
Can someone help me with this?
Thank you.
Ravi
