Ploting a matrix
Sorry for the mistake. As you probably already guesed, I am just starting using R. I could not name the difference between a matrix and a data.frame. > str(b) 'data.frame': 9 obs. of 7 variables: $ Datum: Factor w/ 9 levels "06.03.","07.03.",..: 1 2 3 4 5 6 7 8 9 $ X1 : int 408 335 2123 4685 7669 17060 31330 70730 109667 $ X2 : int 230 241 1509 2226 7839 13997 24797 53133 93061 $ X3 : int 25 16 38 61 114 299 140 172 196 $ X4 : int 248 588 2083 2071 4563 9798 17611 38554 82354 $ X5 : int 407 201 1339 3699 8375 19200 36563 83993 123167 $ X6 : int 248 730 3056 2327 4092 8905 15931 37895 84565 Thanks baptiste auguie schrieb:
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. baptiste On 27 Mar 2009, at 14:54, skrug wrote:
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\\?bungen\\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()

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?
