[R] Plot a matrix recursively

[alcesgabbo]

Hi,

I have the following matrix (named m):
                        key
     sensor_date                              Laser_1              Laser_2          
Laser_3

I plot the first column with the following function:
plot(m[,1],type="o", xaxt="n",ylim=c(min(m[,1:length(colnames(m))])-1,
max(m[,1:length(colnames(m))])+1))

for the other columns I use there functions:

lines(m[,2],type=\"o\")

lines(m[,3],type=\"o\")

ok, it works.

But is there a way to do this prodcedures recursively??

for example:

for each columns {
 lines(m[,column],type=\"o\")
}

I try with :

lines(m[,2:length(colnames(m))],type=\"o\")

but it doesn't work.

Thanks .
Alberto
