retrieve rows from frame assuming criterion [corrected]
Still wrong:
> x <- data.frame(a = sample(letters[1:3], 10, replace=T), b=1:10)
> x
a b
1 a 1
2 a 2
3 b 3
4 b 4
5 a 5
6 a 6
7 b 7
8 b 8
9 b 9
10 c 10
> subset(x, a == c("b", "c"))
a b
3 b 3
7 b 7
9 b 9
10 c 10
> subset(x, a %in% c("b", "c"))
a b
3 b 3
4 b 4
7 b 7
8 b 8
9 b 9
10 c 10

retrieve rows from frame assuming criterion
Hi all,
I have a data frame in which one column(PUNTAR) is of character type.
What I want is to retrieve is the frame but only with those rows matching elements of PUNTAR with a list characters (e.g c("IX49","IX48") )
Year TUR STODNR PUNTAR
1994 9412 94020061 IX49
1994 9412 94020062 IX48
1994 9412 94020063 X32

for (i in ...) { df[[i]]<- .....}
R-help,
In the following loop :
for(i in 1:8)
{
cc[[i]]<-tapply(test[,i+6],list(puntar=test$puntar),sum)/tapply(test[,5],list(puntar=test$puntar),sum)
cbind.data.frame(cc[[1]],cc[[2]],cc[[3]],cc[[4]],
cc[[5]],c[[6]],cc[[7]],cc[[8]])
}
Is there anyway I can 'cbind.data.frame' the objects cc[[ i ]] without
actually writing every single element??
In this case there are 8 but what if

R: Small fixes needed for Riello driver
But the diff file that I'll now produce is related to the 3857 revision, so is also
inclusive of previous changes (i.e. BYTE to uint8_t). Is it Ok for you?
In alternatively could you modify the row (166 of riello_ser.c) of the file deleting the only cast that exist?

boxplot will remember the factor levels
R-help,
I'm trying to do a simple box-and-whisker plot to some data.
The data are a subset of a large data frame
but when running the "boxplot" function on the subset data
all the factors are still present in the graph leaving a huge
empty space until the actuals factors are shown.
This produces a spurious box-and-whisker plot.
If the subset data are exported to another R session

RODBC package -- sqlQuery(channel,.....,nullstring=0)stillgives NA's
(1) I do read the posting guide (the fact that I missread o
missunderstood something does not imply not reading)
(2) I could change NAs to 0 (I know) but I have previously (older
versions of R and SQL*Plus) used the same select with the "right" output
(namely with 0s).
(3) AFAIK "strange" is not a negative remark and does not seem to me at

unexpected behaviour of 'curve' function
Dear all,
curve(x^3*(1-x)^7, from = 0, to = 1)
works as expected but, omitting the "xlim" or the "to"
and "from" arguments and calling "curve" more than once:
par(mfrow = c(2,2))
for (i in 1:4)
curve(x^3*(1-x)^7)
gives an expected (al least to me) result.
Note also that a "pu" object is returned by curve

Where to see a printer...
I installed a printer, HP DeskJet 6122, which has no
Ethernet device inside. In Windows, I use a local port
with address \\darkstar\hp6122. The printer work,
but I can see it only in Windows menu "Fax and Printers",
not in the share resource of Samba, even if I set
my smb.conf with "load printers" and, in [printers].
"browseable = yes" Is it all ok?
Thanx

RODBC package -- sqlQuery(channel,.....,nullstring=0) stillgives NA's
There is something strange in R behaviour (perhaps).
I have run the same select in Oracle SQL*Plus (version 10.1.0.2.0) and
the output comes out with NULLs (which is what it ougth to be).
But in R I still get the same result with NAs (no matter I use
na.strings or nullstring arguments)
An output example follows below:
Using na.string="0" and nullstring="0" (sorry by the

Out of curiosity, why would that be the case?

Using Asterisk with fiber optic
Hi, I'd like to use PSTN and analogic telephone with a Asterisk server which
works on a LAN connected to the outside with fiber optic, on which voice
stream passes too. Do I need some particular solution, some particular card
to make it works or I just need a Digium or similar fxo card?
Thanks,
Bob

LVM use for Xen
Hi.
I''m going to install a testing machine with Xen on Debian Sarge.
I wish to use LVM to partition the hard disk to be able to resize LVM partitions to create new partitions for new domU when I will create new ones.
How I can configure LVM at Debian installation to obtain this?
Could you advise me a partitioning scheme, please?
Thank you very much and goodbye!
