Dear Rusers, I have some data in .csv file like "2004-8-1" and "2004-10-1", and i need to convert them into days from the origin (January 1, 1960). I have tried the function date.mmddyyyy(), but cannot get it. Anybody can show me how to handle the date data? Thanks very much! My dataset like: time 2004-8-1 2004-10-1 2001-9-1 2002-9-1 -- With Kind Regards,

Dear R users, I hope to explain the concepts of skewness and kurtosis by generating series of distributions with same skewness and different kurtosis or with same kurtosis and different skewness, but it seems that i cannot find the right functions. I have searched the mailing list, but no answers were found. Is it possible to do that in R? Which function could be used? Thanks a lot. --

Dear all, I have two variables, y and x. It seems that the relationship between them is Piecewise Linear Functions. The cutpoint is 20. That is, when x<20, there is a linear relationship between y and x; while x>=20, there is another different linear relationship between them. How can i specify their relationships in R correctly? # glm(y~I(x<20)+I(x>=20),family = binomial, data =

Dear Ruser, I use abline() function to add the reference line successfully, but i can't display the values corresponding to the reference line on the x/y axis, anybody knows how to display it? *My simulated programs:* y<-rnorm(50) plot(x,y) abline(v=0.5) *#my question is how to display x=0.5 in the x axis?* Thanks in advance. -- With Kind Regards, oooO::::::::: (..):::::::::

Dear friends, Anybody has ever met the problem to add a legend to a figure generated by image()? I have three variables,x,y and z. x and y are the coordinates, and z is the third values. we can use image(x, y, z,...) to generate a figure according to the z-values, but the problem is the figure legend. How can the legend be added to a figure generated by image()? Note that filled.contour() can

Hi ! While browsing Linux manpages (man 3 syslog) I noticed that the manual says that the LOG_AUTH facility is deprecated use LOG_AUTHPRIV instead. Is there a good reason why OpenSSH doesn't have an option to use LOG_AUTHPRIV facility ? (Looks like that tcpd/telnet etc. use the AUTHPRIV facility (in RH6.2)). Shouldn't be too hard to add the AUTH_PRIV facility ? Cheers, -Jarno --

Dear friends, The following is an example to explain my question. I want to get a legend which will show the z-values according to different colors in image() function. x<-sort(runif(10)) #x-coordinates y<-sort(runif(10)) #y-coordinates z<-matrix(runif(100),nrow=10) #attributes values image(x,y,z,col=gray((6:3)/6)) # legend(x,y,legend=z,col=gray((6:3)/6)) #error. the colors should

Dear friends, After fitting a generalized linear models ,i hope to get the variance of alpha,variance of beta and their covariance, that is , the variance-covariance matrix/information of alpha and beta , suppose *B* is the object of GLMs, i use attributes(B) to look for the options ,but can't find it, anybody knows how to get it? > attributes(B) $names [1] "coefficients"

Dear friends, My dataset is like the following: x y mcpvalue 0.4603578 0.6247629 1.001 0.4603715 0.6247788 1.001 0.4603852 0.6247948 1.001 0.4110561 0.5664841 0.995 The x and y variables are unsorted. I use the function image(x,y,mcpvalue) to generate a plot, but the error is that "increasing 'x' and

Dear all, Following the help from gam(mgcv) help page, i tried to analyze my dataset with all the default arguments. Unfortunately, it can't be run successfully. I list the errors below. #m.gam<-gam(mark~s(x,y)+s(lstday2004)+s(slope)+s(ndvi2004)+s(elevation)+s(disbinary),family=binomial(logit),data=point)

Dear friends, In S-PLUS, we can use the following argument, but not in R. mode12 <- gam(score1 ~ lo(latitude) + lo(longitude)) I searched the help in S-PLUS, it says lo() Allows the user to specify a Loess fit in a GAM formula, but i didn't find the correponding function in R. Anybody knows how to do the similar task in R? Thanks very much. -- With Kind Regards, oooO:::::::::

Dear R users, We have some programs for the specific task in our research, but they were very commonly used. We want to make some functions for them, anybody can recommend any good tools to facilitate us to create R functions even without going deep into the theories of R functions ? Any suggestions or help are greatly appreciated. -- With Kind Regards, oooO::::::::: (..):::::::::

Dear all, Some functions like 'ROC(Epi)' can be used to perform ROC analyssi, but it needs us to specify the fitting model in the argument. Now i have got the predicted p-values (0,1) for the 0/1 response variable using some other approach, see the following example dataset: id mark predict.pvalue 1 1 0.927 2 0 0.928 3 1 0.928 ..................

Buenas tardes a todos. Mi problema es el siguiente: Calculo una muestra de unos índices (s) y a partir de esa muestra elijo aquellos elementos de una tabla de datos que tengo (en este caso XP4) que cumplen la condición de que el índice de XYP sea el de la muestra. Ahora comienza mi problema, la única forma que he encontrado para que me R me tome todos los elementos que necesito es creando un

Hello all, I have a Xen server with 6 network interfaces, I want a bridge on all of them. I use a personal network script like this : #!/bin/bash dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0 "$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=xenbr1 "$dir/network-bridge" "$@"

Hello ! I've a problem with files which are set to 0555. For example: two users (user1 and user2) two groups (usergroup1 usergroup2) /daten/rechner/comp1 is set to 777. User1 creates a file (test.txt) in the [files] share, which is correctly set to 0555. It's owner is user1 and it's group is usergroup1. Now user2 from usergroup2, who can correctly read but not edit

Dear Rusers, I have met a difficult problem on explaining the differences of principal component analysis(PCA) between R,S-PLUS and SAS/STATA/SPSS, which wasn't met before. Althought they have got the same eigenvalues, their coeffiecients were different. First, I list my results from R,S-PLUS and SAS/STATA/SPSS, and then show the original dataset, hoping sb. to try and explain it.

Hello, I wants to make a self compiled kernel for my domUs on a debian etch server with Xen 3.1.4 and 2.6.18.8 dom0 kernel. So, I download sources for linux-2.6.26.8, and I enabled all the Xen features : Symbol: HVC_XEN [=y] Symbol: XEN_BALLOON [=y] Symbol: XEN_FBDEV_FRONTEND [=y] Symbol: XEN_SCRUB_PAGES [=y] Symbol: XEN_KBDDEV_FRONTEND [=y] Symbol: XEN_BLKDEV_FRONTEND [=y] Symbol:

Hi ! I have followed the Samba-Howto, but I still have some problems. Our network is composed of Win2K stations and two samba servers (2.2.5) running under SuSE Linux 8.1. HIROSHIMAN is configured as PDC (domaine CHERYLNET) and everything is running fine, from login to share and printer access. VLOUCHI is a second file server and its workgroup (thus domain) is also CHERYLNET ; security is

How can I disable the roaming profiles that are stored on the server? I'm running samba2.2.3a with about 40 clients consisting of Win98 & W2k machines. My Linux disk keeps running out of space and I don't really need the profiles to be duplicated on the server. I've commented the logon path line in smb.conf and tried 'logon path = ""'. It didn't seem to work.
