Dear All, Suppose I have a categorical variable a=as.factor(sample(1:3,10,replace=T)) plot(a) and hist(as.numeric(a),freq=F) would give the histogram of it. But I do not know how to add the counts or percentage information for plot.factor(). hist() can do it but as a numeric variable, the x-axis is not 3 categories in this case. Thank you for any suggestion. Best wishes, Jie

Dear All, I would like to store quote as part of an vector. For instance, I would like to get an character object as x = " 12"ab"34 " or y = c("1", "2", """, "a", "b", """, "3", "4") Is that possible? Thank you. Best wishes, Jie [[alternative HTML version deleted]]

Dear All, This might be a tiny question but I do not know the reason. On my desktop, sometimes when I use the mouse or ctrl+A select a piece of R script, and use ctrl+R to run it, there is no action. If I redo it, it may work. On my laptop, it is fine. Both are running windows 7. Best wishes, Jie [[alternative HTML version deleted]]

Dear All, I am running a r code on 32bit win, involving absolutely small numbers. Although I tried sth like the ratio of numers like 10^(-100) and did not have issue to get the correct answer, but still a little concerned about it. Could anyone give some suggestion or have any experience? Best wishes, Jie [[alternative HTML version deleted]]

Dear All, I performed thousands of testings and obtained p-values. And then I did two-sided uniform KS test of the p-values, the result claimed it is uniform. So does it mean that my model are wrong? Because I expect more small p-values near 0. This is a preliminary step before correcting the multiplicity. Attached is hist of p-values (does this list allow attachment?). The ks test: One-sample

Dear All, I have a long sequence and want to find the quantile, or sort it first. It seems sort() or quantile() reaches the memory limit. Is there a way to allocate more memoy on SSD for R when startup, so that R can use both RAM and hard drive space? Thank you. Best wishes, Jie

Dear All, I have three classes of questions about generating random numbers with different packages (windows xp 32bit R). . 1. Suppose I would like to use package *foreach*, can I use current Sys.time as a seed? Although I can get the time up to1e-6 second precesion, the code below dose not work well on a local machine with two cores. ################# library(foreach) library(snow)

Dear All, I have a question, suppose X is a dataframe, with column names as "x1", "x2", "x3", ..... And I would like to use the i-th column by X[,'xi']. But it seems the single quote and double quote are different. So if I run X[, names(X)[i]], it has some error. Please use the below example code X = matrix(rnorm(50),ncol = 5) X = data.frame(X)

Dear All, Suppose I have a program as below: Outside is a loop for simulation (with random generated data), inside there are several sapply()'s (10~100) over the data and something else, but these sapply's have to be sequential. And each sapply do not involve very intensive calculation (a few seconds only). So the outside loop takes minutes to finish one iteration. I guess the better way

Dear All, I am learning parallel in R and start with the package "snow". I did a test about running time and the parallel version is much slower than the regulat code. My laptop is X200s with dual core intel L9400 cpu. Should I make more clusters than 2? Or how to improve the performance? # install.packages("snow") library(snow) cl <- makeCluster(2) t1 <- proc.time() a

Hi together, when I´m starting a VM my host freezes gradually. This seems to happen because its running out of memory and no other process is able to do anything. I have 16GB of ram in total. 8GB are reserved for hugepages. So for the daily business on the host I have 8GB left. I don´t run many or extraordinary consuming software on the host - normally just a gnome session and the chromium

Hi All, I have millions of regression lines to fit. So I am looking for the most efficient approach in R. Details: I have a large desing matrix X. The dimension is n by p. Each time when fitting the model, select rows from this matrix X and form a new design matrix, called X_current. There is another binary matrix M, with dim m by n, and each row is a 1*n vector. It helps to determin X_current.

Hi Craig, Thanks for the information. Can you point to the source that specifies tGPR to be R0 - R7? I tried to search in ARMInstrThumb.td but couldn’t find it.

Martin, Just a minor fix. Jie, Try the -r option (or the --recurse) option instead. It looks like the source changed to this: options.c: {"recurse", 'r', POPT_ARG_NONE, &recurse}, But the help is still at: options.c: rprintf(F," -r, --recursive recurse into directories\n"); eric Jie Gao wrote: > > rsync: --recursive:

Sorry for not being specific enough. ARMv7-M includes Thumb and Thumb2. It has 12 regular registers (R0 - R12), and R8 - R12 are used. I can generate mov instruction that from/ R8-R12 to/from R0-R6. From this ARM page http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0068b/ch03s03s01.html R9 - R12 have their conventional usage, but I don’t if this is the reason we cannot use them

Hi All, I've got a cron-run rsync (2.4.6) hang on both sides (solaris to solaris). The platform is: SunOS 5.7 Generic_106541-12 sun4u sparc SUNW,Ultra-80 Sorry if this has been asked before, for I couldn't find a searchable archive for this list on . Regards, Jie

Hi Han, thanks for your reply. I'm using KVM as hypervisor. The versions are: Kernel: 4.5.2 Libvirt: 1.3.4-1 But its quite embarrasing... when I was answering your mail I was having a look if there is a new kernel I can build, since I have to rely on some patches. I upgraded from 4.4.3 to 4.5.2 and now libvirt doesn´t have any problem. So thanks for the heads up! Regards Alex On Tue, May

hi R user mtdno<-paste("data",1:3,sep="") tyno<-paste("obs",1:5,sep="") flnm<-paste(mtdno,tyno,"_err.dat",sep="") flnm is [1] "data1obs1_err.dat" "data2obs2_err.dat" "data3obs3_err.dat" [4] "data1obs4_err.dat" "data2obs5_err.dat" but actually what i want is data from 1 to 3
