levels of factor
R-help,
I have a data frame wich I subset like :
a <- subset(df,df$"column2" %in% c("factor1","factor2") & df$"column2"==1)
But when I type levels(a$"column2") I still get the same levels as in df (my original data frame)
Why is that?
Is it right?

fill up a matrix
Hi all,
I want to fill in this matrix vectors (by column) without overwriting the first elements in column 1995.
Is there any other way than concatenate the first element with the vector and then assign this new vector
to the column in matrix?
matrix[,"3"]<-c(1591,"vector")
matrix[,"4"]<-c(405,"vector")

How to sort TWO columns ?
Dear ALL,
I fear my question has already been answered many times before, but I
haven't fund that in archives...
I am working on spatial datasets and, in most arrays I'm handling, there are
two columns dedicated to (x,y)-coords.
For different reasons - notably to draw image() plots, I need to have these
two columns sorted in increasing order.
But sort() and order() seem to apply to

R and excell differences in calculation F distributionfunction
R-help,
I'm trying to work out the density function by doing:
> df(5.22245, 3, 22)
[1] 0.005896862
> df(15.20675, 6, 4)
[1] 0.001223825
In excell the result is :
0.0071060464 <*> FDIST(5.22245,3,22)
0.0100001406 <--> FDIST(15.20675,6,4)
>From my point of view the differences in the second case
are substantial.
Can anyone give me a hint on this?
Thanks in

function output
I have the next function :
"extracting.lgddata"<-function(channel)
{
library(RODBC)
channel<-odbcDriverConnect("")
.......
.......
}
...... is just a sequence of SQL selects.
But when I try to call the objects created from the select they do not seem to have been created.
I checked with ls() and they actually do not exist.
What is the problem?
Thank you

function(...) {}
R-help
Assignments within functions are local and temporary,right?(function 1)
If arguments to another function (function 2) are objects created in function 1 and need to call function 2,,,,,,,then it won't work,Am i right?
I have nested the functions but still do not work.
How can this (it may be simple but I don' know how to get around this) be done??

De alguna manera R (a través de RStudio) no está incorporando el directorio

problema con RStudio
Hola, ¿qué tal?
¿Puedes comparar la salida del comando
Sys.getenv("LD_LIBRARY_PATH")
en una sesión en la que funciona RODBC y otra en la que obtienes el
error anterior?
Un saludo,

P.D.: A propósito, también he estado tratando de utilizar RODBC en
Linux y me he acabado rindiendo. Sobre todo porque RJDBC funciona
bastante bien.
