Subscribers,
For this example:
library(lattice)
testmatrix-matrix(c(1,2,3,4,3,6,12,24),nrow=4,ncol=2)
testylabels-c('w1','x1','y1','z1')
dotplot(testmatrix, scales=list(y=list(labels=testylabels), xlab=NULL))
legend('bottomright', 'legend', col=c('blue', 'pink'))
Error in strwidth(legend, units
Subscribers,
What is my mistake with the following example:
library(lattice)
testmatrix-matrix(c(1,2,3,4,3,6,12,24),nrow=4,ncol=2)
testylabels-c('w1','x1','y1','z1')
dotplot(testmatrix, scales=list(y=list(testylabels)), xlab=NULL)
#testylabels not shown, instead 'D' 'C' 'B' 'A'
Thanks in
Subscribers,
A spreadsheet contains (what appears to a low aptitude mathematician!) a
recurrence equation:
cellb1=2cellc1=0.1 celld1=5
cella2=1/(k1*cellb1)cellb2=cellb1+cellc1+celld1 cellc2=cella2*cellb2
celld2=cellb2*k2
where k are constants.

No such log file exist and other files in the directory do not make
reference to R and any general errors (e.g. internet access).

What is the correct syntax to apply the 'if else' conditional statement
to vector objects?
Example:
vectorx-c(50,50,20,70)
vectory-c(50,50,20,20)
vectorz-function () {
if (vectorxvectory)
vectorx
else vectorx-0
}
vectorz()

Subscribers,
For a menu:
menu(c('a','b','c','d'))
How to create a function that will apply to specific menu choice
objects? For example:
object1-function (menuifchoices) {
menu1-menu(c('a','b','c','d'))
