changing "," to "." in data.frame
...,
fff<-function(x) gsub(",", ".", x)
BX <- apply(apply(AX, 2, fff), 2, as.numeric)
this seems to be easier.
Cheers

Error term in aov syntax question
...t 3) in my dataset :-(.
But if I had more data in one measurement (let say three fractions in each of three
samples),
is the correct aov syntax for such problem like this:
summary(aov(h~frakce+vzor+Error(mereni/(frakce+vzor))))
Thanks a lot

Problem using outer()
Here is a problem I am having. I would sincerely appreciate any help/advice
from the experts who read this list. I have contrived a simple example, but
it gives the same result I encountered in a more complicated application.
Given data frame u:
x y
31 19
32 18
33 17
34 16
35 15
36 14
37 13
I define the function f as follows:
f <- function(a,b) sum(u$x - a) + sum(u$y - b)

Plotting factors in graph panel
Thanks! You are correct, the graphs look very similar, except ggplot is
scaling the text font to make it more readable. Is there a way to scale
down the x-axis labels, so they are readable?
