the result of read.table is a data.frame, not a matrix as you first
suggested. Can you copy the result of str(b) so we know what your data
is made of?
I'm guessing the most elegant solution will be to use the reshape
package, followed by ggplot2 or lattice.

Unfortunately, I could not solve the problem of plotting all columns
of
a matrix against the first column
I used:
b=read.table("d:\\programme\\R\\übungen\\Block 1b.txt", header=T)
"b" is a table with the first column using Dates and the following
columns with vectors.
apply(b[,-1], 2, plot, x= b[,1])
Also all columns have the same length, [R] states that the length are
different.
Can you help me?

Something like this perhaps,
a <- matrix(rnorm(5*49), ncol=49)
pdf(width=15, height=15)
par(mfrow= c(8,6))
apply(a[,-1], 2, plot, x= a[,1])
dev.off()
HTH,

Hi evrybody,
in a matrix consisting of 49 columns, I would like to plot all
columns
against the first in 48 different graphs.
Can you help me?
Thank you in advance
