Moving the system from 5.3 to 5.4
Hello, I built a system based on centos 5.3, now i'm planing to move to 5.4. To do it I rebuilt all rpms making some changes. When I use a common centos 5.3, it automatically detects that 5.4 is available and move update for it when i run yum update. How does this work? How the system detects new version and update for it? I thought centos-release rpm just update repo for it, but I saw this

Writing Text into Plots
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I have a simple question on the text() method in plots, e.g.: text(3,4,adj=1,cex=1.0, expression(alpha == beta)) I know there exists a lot more like frac(), etc which could be used for expression. But a help(frac) doesn't return any results - where do I have to look for a documentation of possible text commands? More in detail I'm

ENC: Using lm() combined with sapply
Hi Caio, I just replied to a fellow who needed to run a series of regressions changing the dependent variables for the same period. I believe your solution might be similar to that one, just making the window dynamic instead. I used a lapply to store regressions and sapplys to extract stats from the lm()s. Please check the attachment and hope it?s useful. Filipe Botelho -----Mensagem

Can't mix high level and low level plot functions.
Hey R-Comunity, I'd like to print out an histogram of some experimental data and add a smooth curve of a normal distribution with an ideally generated population having the same mean and standard deviation like the experimental data. The experimental data is set as vector x and its name is set to group.name. I paint the histogram as follows: hist(data, freq=FALSE,
