Hi,
I would like to convert my "character" sequences in my matrix/
data.frame into "numeric" where it is possible.
I would also like to retain my alphabetic character strings in their
original forms.
"5.1" > 5.1
"hm" > "hm"
k<-matrix(c("aa", "bb", 1,2, 4.3, 0), nrow=2)
mode(k) <- "nume
Thanks for the answer.
Surely, without popping windows it is a lot more convenient.
This piece of code seems to work for me.
def.par <- par(no.readonly = TRUE)
png(file="thisPlot.png", width = 1200, height = 800, units = "px",
pointsize = 12)
plot(blah-blah...
dev.off()
par(def.par)

Dear list,
This is not a question but a rather short note how to save a plot
if it was created in batch mode.
It took me like 2 hours to figure it out, I hope it can save time
for those who - like me - are not really fast in picking up
diosyncrasies of R. (as far as I remember I had no problems wh
Philipp,
thanks for the tip.

Dear list,
Can somebody tell me how to invoke user-defined functions from script
files during run-time?
Basically I have (almost) one function per script file.
I am thinking of something like
#include in C++
import in Java/Python
use in Perl
No, I don't need my functions every t
Gentlemen,
Thank you for all your help.
This list is really amazing.
Following Erik's hint I have managed to find the answer:
complexFn <- function(a,b){
c <- (a+b)/2
return(c)
}
x <- zoo(1:10)
rollapply(x,width=2, function(xx) complexFn(xx[1],xx[2]))

Dear Erik,
Thank you very much.
Probably it is exactly "zoo" what I have beenlooking for.
Actually "rollapply" looks like something I could use, but...
For some reasons beyond me, the following attempts
in which I tried to apply my home-made 'fun' to rollaply
miserable failed.
complexFn <- funct
Thanks for the replies
Sorry for being unclear.
I am asking if there is a way to process a vector in a way
that uses references to other elements of the same vector.
And doing this without a for-loop.
Here is a running code:
complexFn <- function(a,b){
c <- (a+b)/2
return(c)
}
x <- 1:10

Achim, thank you.
My careless mistake.

Dear list,
Is there a way to do something like the following pseudo-code -
without for loop?
complexFn <- function(a,b){
...
return(c)
}
x[i] = complexFn(x[i-1], x[i-2])
I have found "filter" but would like to do something more complicated
than multiplication with x[i-1] and x[i-2].
Thank
from the top of my head (ugly but works).
jumps 5 if i==2 or i==8
j = 0
for(i in 1:15){
if((i==2)||(i==8)){
print(i)
j=i+5
next
}
if (i>=j){
print(i)
}else{
next
}
}
