Hello, I wonder when I do coxph in R: coxph( Surv(start, stop, event) ~ x, data=test) If x is a categorical varible (1,2,3,4,5), should I creat four dummy varibles for it? if yes, how can I get the overall p value on x other than for each dummy variable? Thanks Lisa Wang Princess Margaret Hospital Phone 416 946 4501

Dear R listers, I have a data file looks like the following: Testing marker: s_1 --------------------------------------------- Allele df(0) -LnLk(0) df(T) -LnLk(T) ChiSq p 3 7995 29320.30 7994 29311.85 16.90 4e-05 (2229/8000 probands) Testing marker: s_2 --------------------------------------------- Allele df(0)

Dear R-help, Let's say `x1' and `x2' are very long vectors (length=5e5, say) with same set of names but in different order. If I want to sort `x2' in the order of `x1', I would do x2[names(x1)] but the amount of time that takes is quite prohibitive! Does anyone have any suggestion on a more efficient way to do this? If the two vectors are exactly the same length (as I

Below are the results for the Polyhedron 2005 benchmarks compiled with the llvm/compiler-rt/dragonegg 3.3 release and 3.4svn against FSF gcc 4.8.2. The *-stock-de runs omit the -fplugin-arg-dragonegg-enable-gcc-optzns flag and the *-de-optnz runs include it. There seems to be little improvement between llvm 3.3 and 3.4 in the stock case which relies entirely on llvm for vectorization. Duncan, has

I set sshd to deny root login. But I still get a password prompt! So if I get the password right, I get one error message: Received disconnect: ROOT LOGIN REFUSED FROM example.com while if I simply put in a wrong password three times I get Permission denied. If this means I set it up wrong please mail me directly - I'm not subscribed to the list. Otherwise please fix this. -- The

I have just upgraded my server from CentOS 5 to CentOS 6 and am having connectivity problems. My laptop runs Fedora 14, and I have been in the habit of mounting data partitions on my server by fstab entries. Since the update I've not been able to do that. On watching the messages during a reboot I saw a statement that the connection was denied by the server (where are those messages

Hello everyone! I have a data frame of 136 variables with 270 observations. I would like to create a new data frame such that each element of that data frame contains the maximum value of the 6 prior lags of the initial data frame. So for example, if my original data frame, A, were A1=c(7.72, 7.94, 7.56, 7.54, 0.93, 0.59, 7.21, 8.00, 7.19, 7.57)A2=c(4.27, 3.70, 3.80, 3.67, 3.83, 3.95, 4.02, 2.06,

Thanks for your kind reply. Problem is solved. However, it's "confidence interval / treatment comparison plot" is not taking main title. And the fonts of axes labels can not be changed using 'cex' parameter. I will appreciate if you could help in this matter too. Dr. A. K.

Hi,. I've installed RSPerl on my Linux box. It runs all of the test scripts that I've been able to find. I've learned that I can pass in vectors of data as array-refs, and can use named parameters with R::callWithNames and a hash of names and values. The one problem that I'm left with is how to call a function from an add-on package ('ctest' in this case). I know that

Hi, I need further help with my GAMs. Most models I test are very obviously non-linear. Yet, to be on the safe side, I report the significance of the smooth (default output of mgcv's summary.gam) and confirm it deviates significantly from linearity. I do the latter by fitting a second model where the same predictor is entered without the s(), and then use anova.gam to compare the

Hi People I just updated a CentOS 5.2 Server that is a Guest inside VMware ESX 3.50 Server using "yum update".

Hi all. As Corinna pointed out, there are some cases where sshd will log some authentications twice when privsep=yes. This can happen on any platform although it seems most obvious on the ones that don't do post-auth privsep. It also occurs when sshd logs to stderr (eg running under daemontools) or when you have a /dev/log in the privsep chroot. The patch below attempts to solve this for

Hello, I try to handle the data using read.csv , zoo and aggregate functions. The data contains NA values. After aggregating monthly data into quarterly data, all data become NA. Is it because I don't properly aggregate the data in the presence of NAs? What can I do? Another problem is that the date in month is presented in Chinese (My OS is in Chinese.) How can I set the default

Any help would be most appreciated. (Don't make me get down on my hands and knees and beg for help, cause I'll do it!!) My boss has me learning R and doing nested regression with the report due Mon (Friday night statistics...fun. ). Anyway, here's my problem: In a regression equation not accounting for the fact that people are nested in families, the result for Z variable is VERY
