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
