Does this example help?
a <- matrix(letters[1:12], ncol=3)
a
[,1] [,2] [,3]
[1,] "a" "e" "i"
[2,] "b" "f" "j"
[3,] "c" "g" "k"
[4,] "d" "h" "l"
write.table(a[,3,drop=FALSE],quote=FALSE,col.names=FALSE,row.names=FALSE)
i
j
k
l

Thank you Dieter and Rolf,
I have solved the slash Problem, but I still struggling with the output
files.
I have tried this
by(AlexETF,AlexETF$Industry,function(a) {filename = paste("C:/ab/",gsub("
","",a$Industry[1]),".txt",sep="")
print(filename)
write.table(a,file=filename,col.names = FALSE)
}
)
and this
by(AlexETF,AlexETF$Industry,function(a) {filename = paste("C:/ab/",gsub("
","",a$Industry[1]),".txt",sep="")
print(filename)
write(as.character(a),file=filename)
}
)
I want in each file just the ticker with out any quotations mark.
