data.frame-question]
...ng style, could you please be more specific
about where the error occurs as without this it is very difficult to
identify what the problem is.
Now concerning your problem. When I tried the code I posted yesterday I
thought it worked fine. I've tried it again now and found that the
data.frame TAB3 actually only has one column and the names "A", "B" etc are
actually interpreted as the row names. Since there is only one column the
'colnames(TAB3) <-' fails when you give it a vector with two components. I
think that if you display it without renaming the columns...

Problem to read non-standard csv file
Hi all,
I have a problem to read csv file with comma as decimal. The numbers were
readed as strings.
I used the following string in R, but I do not understand why it does not
work.
tab <- read.csv2("Specimen_RawData_1.csv", header = TRUE, sep = ";", dec =
",", nrows = -1)
In addition, I copy/past into the post the link to the csv file generated by
my instrument.

apply on large arrays
...table, approximately of size 60*2*500*500,
and I need to count the number of cells containing a count of 1 for each
of the factors values defining the first dimension.
Here is my attempt:
tab1<-with(pisa1,table(CNT,GENDER,ISCOF,ISCOM))
tab2<-apply(tab1,1:4,function(x)ifelse(sum(x)==1,1,0))
tab3<-apply(tab2,1,sum)
Computing tab2 is very slow.
Is there a faster and/or more elegant way of doing this?

data.frame-question
...e_singular<-as.character (Name_singular)
TAB2<-data.frame (Name_singular)
# it looks like this:
Name_singular
A
B
C
D
E
-My result should be a data-frame, where the first column is
Name_singular and the second column should be the sum of the numbers
where Name ==Name_singular.-
For example:
TAB3:
Name_singular Sum
A 11
B 27
佲仸
- I tried it with for-loops, but I think there must be an easier way.-
I would be very grateful for your help,

How to best divide table by table
Hi all,
how can I divide two tables of the same dimension so that all names are
preserved, ie do not become NA? I have "tab1" and "tab2", each having
names in the first column. I want "tab3" with the same names and values
"tab1/tab2".
Thanks,

I tried the program:
M?dias = matrix(NA, nrow(tab1), ncol(tab1))
for(i in 1:nrow(tab1)){
for(j in 1:ncol(tab1)){

M?dias = tab1$i[j]
}}}}

loop and read.table
Hi,
I would like to open several tables with a loop, using something like :

Error in file(file, "r") : unable to open connection
In addition: Warning message:

ctrl-c doesn''t work in domU consoles
Hey,
I''ve installed Xen 3.0 on a freshly installed Debian Sarge. dom0 is
working nicely (kernel 2.6.12.6-xen0). Then I created a domU, again with
Debian Sarge, booting Xen''s vmlinuz-2.6.12-xenU. Unfortunately ctrl-c
does not work in the domU''s console, neither if I create the domU
with "xm create -c ..." nor if I attach to it later. It doesn''t matter

[PATCH 00/45] initial arm v8 (64-bit) support
First off, Apologies for the massive patch series...
This series boots a 32-bit dom0 kernel to a command prompt on an ARMv8
(AArch64) model. The kernel is the same one as I am currently using with
the 32 bit hypervisor
I haven''t yet tried starting a guest or anything super advanced like
that ;-). Also there is not real support for 64-bit domains at all,
although in one or two places I
