Transparent Bands in R
Hello All, My question is regarding the attached plot. I would like to have multiple transparent green bands running the length (yaxis) of the plot the width of which is determined by the green lines at y=0 in the plot. Can you suggest a way to do it? For those who can't or are unwilling to download the file the plot is at http://www.twitpic.com/ma8w0 Thanks!

Re-execute previous command
Hello All, In bash, to re-execute a command, say, 'gnuplot plot.gnu', one can type !gnu. Is there a similar feature in the R console? For example: plot(g1$mean,g2$mean) . . . Lines, many lines of commands ->Here I want to repeat the previous plot command. !plot and plot(+TAB) do not work. This question was asked in this forum back in 2006 but the answer seems to have been lost

Create subsets of data
Hello All, Let's say I have points on a x-y plane. x ranges from 0-2 and y from 0-2. There are points in quadrants x[0:1]---y[0:1] and in x[1:2]----y[1:2]. I would like to get the mean and std of the points in the x[0:1]----y[0:1] quadrant alone. Is there a straight forward way to do it? I asked a similar question a few days ago regarding plotting a subset of data using conditions. The

[Pv-ops][PATCH 0/4 v4] Netback multiple threads support
This is netback multithread support patchset version 4. Main Changes from v3: 1. Patchset is against xen/next tree. 2. Merge group and idx into netif->mapping. 3. Use vmalloc to allocate netbk structures. Main Changes from v2: 1. Merge "group" and "idx" into "netif->mapping", therefore page_ext is not used now. 2. Put netbk_add_netif() and netbk_remove_netif()

samba 4.x slow ...
Hi, we are running samba 4.4 on two machines as file servers. Both are running a GFS (stornext). The storage is attached using 8G HBA. You can get up to 800MB/s local speed. We are exporting the shares using 2x1GB and 2x10G. However the clients are only getting 40-50MB/s. With samba3 I think we had up to 80-90MB/s. Using a 100MB/s link for the client we see 12-13MB/s (wire speed). Using

[OT] Shaping and squid question
List Out of interest, I use transparent squid proxies for caching websites, and I shape the clients that browse the net, this all works perfectly so no questions in this regard... CLIENT <--- eth0 ----> SQUID <----- ppp0 -----> NET What I just realised was that all egress traffic on eth0 gets shaped, squid gets data from ppp0 and hence is not shaped. Does this mean that squid

Persistent state of R
Hi I am using R as a back-end to some CGI scripts, written in Perl. My platform is Suse Linux 8.2, Apache 1.3.7. So the CGI script takes some form parameters, opens a pipe to an R process, loads up some Bioconductor libraries, executes some R commands and takes the ouput and creates a web page. It is all very neat and works well. I am trying to make my cgi scripts quicker and it turns out

Promoting Samba BDC to PDC
Hi All, Has any one got an idea of how to make clients automatically find the BDC when the PDC is stopped. Both PDC and BDC are running by Samba authenticating again a LDAPSAM backend replicated on both the PDC with master LDAP database and BDC with replicated LDAP database. But when I stop PDC the clients are not detecting the BDC broadcast. I can see that the replication is of

If you look into the download areas, you'll find Asterisk 1.0 release candidate two... Find the mirrors on the link below, they'll update during the day if they don't already have RC2. Please don't hit the Digium FTP-server, since development need that connection for the bug tracker and the CVS. (And I guess Digium also needs the link for telephony :-) Mirror listing *
