The entries in xenstore have permission attributes. The attributes can be easily altered by xenstore-chmod, however, I cannot find a easy way to see them. I''ve modified xenstore_client.c to raise a new utility. The utility checks the permission and makes an easy-look output. Please tell me any suggestions. Thanks.

Hey, I'm trying to build something like this http://flowingdata.com/2011/05/11/how-to-map-connections-with-great-circles/ but with my own data in csv files. The code runs well if I use the same csv files as the author, but with mine , this is what I get *Code* library(maps) library(geosphere) map("world") xlim <- c(-180.00, 180.00) ylim <- c(-90.00, 90.00)

Is there a library that is able for example to 1. merge 2 dataframes by row eg.: rbind(dataframe1, dataframe2):data.frame 2. delete a column from a dataframe del(dataframe, colname) or del(dataframe, colindex= 1):data.frame? 3. Select lines from a dataframe by a specific function ? select(dataframe, func=small(x){x<1}, colindex=3): data.frame? 4. converting all double columns of a data.frame

I am fairly new to R and am plotting flight data on a map. Everything is working well except the size of the map is really too small to show the data effectively and I can't seem to figure out how to make the output map larger. Do I need to change the device characteristics or is it a map.??? call. Here is the code: library(maps) library(geosphere) airports <-

Dear all, I am having trouble creating summary tables using aggregate function. given the following table: Var1 Var2 Var3 dummy S1 T1 I 1 S1 T1 I 1 S1 T1 D 1 S1 T1 D 1 S1 T2 I 1 S1 T2 I 1 S1 T2 D 1 S1 T2 D 1 S2

Dear everyone, I have looked all over the internet but I cannot find a way to solve my problem. In my data I want to sum a couple of variables. Some of these variables have NA values, and when I add them together, the result is NA dat <- data.frame( id = gl(5,1), var1 = rnorm(5, 10), var2 = rnorm(5, 7), var3 = rnorm(5, 6), var4 = rnorm(5, 3), var5 = rnorm(5, 8) ) dat[3,3] <- NA dat[4,5]

Hello, I''ve modified tools/xenstore/xenstore_client.c to include a new utility, xenstore-chmod. This utility permits developers and administrators to manually change the permissions on arbitrary locations in XenStore from the command line. This is often helpful if you''re trying to debug an application that relies on XenStore and is encountering difficulties with permissions.

Dear all, I am facing a problem with running a script that i have written in R and i hope you can help me spot which exactly is the problem and how i can solve it.

Dear R-listers, I am a newbie with R and I am struggling with something I consider very basic. I wish to produce a table (to import in a latex file) of summary statistics, but for as much as I've been looking around and trying various alternatives (plyr, reporttools, pastecs and Hmisc) I haven't found what I am looking for. Probably I am doing something wrong, but I can't figure out

I have a forum-type application. The Board model has many comments, the Comments model acts as a tree. So I have a board with multiple comments, some comments are parent comments and there are comments that belong to a parent comment, making up a thread. Like most forums, I want it so that threads are sorted based on the date of their last comment. But I have no idea how to specify this in

Dear list, after fitting an lrm with the Design package (stored as "mymodel") I try running a summary, but I get the following error: dim(mydata) [1] 235 9 names(mydata) [1] "id" "VAR1" "VAR2" "VAR3" "VAR4" "VAR5" "VAR6" "VAR7" "VAR8" summary(mymodel) Error in `contrasts<-`(`*tmp*`,

Hi All, my script tries to do the following on factors: > ## Check for case 3: Umsatz = 0 & Kunde = 1 > for (year in 2011:2015) { + Umsatz <- paste0("Umsatz_", year) + Kunde <- paste0("Kunde01_", year) + Check <- paste0("Check_U_0__Kd_1_", year) + + cat('Creating', Check, 'from', Umsatz, "and", Kunde,

Hello to the whole group. I am a newbie to R, but I got my way through and think it is a lot easier to handle than other software packages (far less clicks necessary). However, I have a problem with respect to the summary of regression results. The summary function gives sth like: Residuals: Min 1Q Median 3Q Max -0.46743 -0.09772 0.01810 0.11175 0.42252

Hi, I have a vector of strings like: c("a1b1","a2b2","a1b2") which I want to spilt into two parts like: c("a1","a2","a2") and c("b1","b2,"b2"). So there is always a first part with a+number and a second part with b+number. Unfortunately there is no separator I could use to directly split the vectors.. Any idea

Javier Muchas gracias por su respuesta Aunque no está funcionando, pues si ejecuto: EncDTE1<- t.EncDTE1[ !is.na(t.EncDTE1$Var1),] obtengo Var1, Var2, Var3,...Varn con datos "texto", NA, NA....NA Pero al ejecutar EncDTE1<- t.EncDTE1[ !is.na(t.EncDTE1$Var2),] obtengo Var1, Var2, Var3,...Varn con datos NA,"texto", NA....NA Estoy tratando de dar la vuelta con el loop

I have a data frame (df) with colums x, y and z. e.g. df <- data.frame(x = sample(4), y = sample(4), z = sample(4)) I can extract column z by: df$z or df[3] I can also extract columns x,y by: df[1:2] or by df[-3]. Is it possible to extract x,y columns in a "symbolic" fashion i.e. by equivalent of df[-z] (which is illegal) ??? Or alternativeley, is there an equivalent of

Hello, I'm trying to make a 3d plot using rgl in which the size and color of each point corresponds to certain attributes of each data point. The color attribute, let's call it X, is scaled to go from 0 to 1. The rainbow(64,start=0.7,end=0.1) palette is perfect for what I want but I don't know how to take that palette and pick a color from it based on the value of X for a given data
