Hi all, I was wondering if there is a function kind of similar that splits a dataframe, applies a function to each row and returns in a data frame. I know ddply but this one isn?t useful in this situation. I have a dataframe with values for each day (rows) for different objects (columns). I have values for several years. Now, I want to do calculations on only the data of that year. With the

Dear list, Following a recent enquiry, I've been playing with the idea of creating a colour gradient for a polygon, using the Grid package. The idea is to draw a number of stripes of different colours, using the grid.clip function. Below is my current attempt at this, library(grid) rotate.polygon <- function(g, angle=0){ # utility function, works fine matR <- matrix(c(cos(angle),

Here are my patches to add extra shapes to the annotate plugin. I have also added dbus support and made a few things configurable. The new tools available are Line, Rectangle and Circle, the original is called Brush. There is no selection line at the moment because I do not understand OpenGL yet. Hopefully these patches can be added and something added later. There is an extra action called

I think I asked a similar question 3 years ago to the Splus list and I think the answer was no or noone answered so noone should spend more than 5 minutes on this because it could definitely be a waste of time. My question is whether the function below can be rewritten without a for loop. apply is fine if it can be done that way but i doubt it. I call it a lot and would prefer to not loop.

Hi, is not there any way to tell grid() the starting value? With nx,ny I get the right number of grid cells, but not on the exact values I would like them. (I know I can do it with abline(), just asking for an easier way, i.e. grid(nx,nx,start.x,start.y)) An alternative way (which would solve another problem) would be making the axes coincident w...

Hi Konrad I encountered a bug when trying to bring offline a cpu then online it again in HVM. As I''m not very familiar with HVM stuffs I cannot come up with a quick fix. The HVM DomU is configured with 4 vcpus. After booting into command prompt, I do following operations. # echo 0 > /sys/devices/system/cpu/cpu3/online # echo 1 > /sys/devices/system/cpu/cpu3/online With

...Archive: http://lists.samba.org/pipermail/samba/ I recently upgraded from RedHat Linux 6.2 running Samba -2.0.6-9 (which was running fine) to RedHat 7.1 and Samba 2.0.10-2. and I am unable to get smbd and nmbd to start. When I use the command: /etc/rc.d/init.d/smb start, the system says it is starting but the daemons are not running. RedHat 7.1 uses xinetd rather than inetd and I have not found any documentation concerning Samba and xinetd. Restarting xinetd does not start the daemons either. I have upgraded to the latest rpm's from the RedHat site with no change. I was wondering...
