Hello,
The following code may help you:
my.matrix <- matrix( rnorm(16), ncol = 4 )
boxplot( my.matrix ~ col( my.matrix ) )
Hii,
I will create boxplots from matrices. I have the following data sets:

200.0 1.79 3.00 1.945 0
The first thing I do is, to run the command
y<-matrix(c(test$V3),ncol=8)
to divide the third column in 8 matrices to create 8 boxplots.
The I run the command
w<-summary(y)
to get the values min, max, mean, median, 1.Quan, 3.Quan
My problem is, I cann't run the plot command to create the 8 boxplots in
a
graph...
The command
plot(y)
gives me an error..
Can anybody help me to create the boxplot from matrices in a graph ?
greetings,
j
