Hi, Each > help.start() generates a new tree of the R help system, somewhere in 127.0.0.1:xxx, each xxx being difeerent. This tree disappears when exiting R. How can the current help tree copied to a permanent place for reference outside a running R? This would be practical for not having to enter M-x R . TIA --Christian -- Christian W.

Hi there, Here is a minimum working example: ---------------------------------------------------------------- lower = 0 upper = 1 n_bins = 50 interval = (upper - lower) / n_bins bins = vector(mode="numeric", length=n_bins) breaks = seq(from=lower + interval, to=upper, by=interval) for(idx in breaks) { bins[idx / interval] = idx } print(bins)

Hi, I have a data.frame like this: y <- rnorm(60) lev <- gl(3,20, labels=paste("lev", 1:3, sep="")) date1 <- as.Date(seq(ISOdate(2007,9,1), ISOdate(2007,11,5), by=60*60*24)) date1 <- date1[-c(3,4,15,34,38,40)] df <- data.frame(lev=lev, date1=date1, y=y) I would like to produce a new data.frame with missing days in df$date1 in each df$lev, like this: lev

Hello, I have a question on how to tabulate the time series data. I use RStudio, but if can be done in any other R editor, it should work in RStudio as well. > a1<-11:22 > a1ts<-ts(a1, frequency=4, start=c(1978,1)) > a1ts Qtr1 Qtr2 Qtr3 Qtr4 1978 11 12 13 14 1979 15 16 17 18 1980 19 20 21 22 If I click the variable "a1ts" on the

Dear All, I am very new to R - trying to teach myself it for some MSc coursework. I am plotting temperature data for two different sites over the same time period which I have downloaded from a university weather station data archive. I am using the following code to create the plot plot ( x = TEMP3[,"TIME"], y = TEMP3[,"TEMP"], type = "p", col =

Hi, I have a rails application where I respond to a request by fetching image urls from various web api calls and need to display them as they come available. I am able to display all the images once I get them all, but that causes an unacceptable delay for my user. One approach I am trying is, from my controller, set an @image variable, and then pass in a block to the model that retrieves the

I want to compute a new variable (newvar) based on the values of two other variables (t1freq, t2freq).The two variables (t1freq,t2freq) are contained in a dataframe - study1dat <- read.csv("c:\\study1rb.csv",header=T) . I gather this computation can be done using Apply and I have run the following example from the help menu ## Compute row and column sums for a matrix: x

Dear R-help, I am trying to estimate a Cox model with nested effects basing on the minimization of the overall AIC; I have two frailties terms, both gamma distributed. There is a error message (theta2 argument misses) and I don?t understand why. I would like to know what I have wrong. Thank you very much for your time. fitM7 <- coxph(Surv(lifespan,censured) ~ south + frailty(id,

Hi there, I am currently working on my dissertation which is about testing the martingale hypothesis in the stock market using a methodology involving a range of variance ratio tests and multiple variance ratio tests. I contacted the author of a reference paper and I was told that the tests can be conducted using R programming language. Although I have gone through the theoretical background of

I have downloaded samba-2.2.2-sparc-solaris-2.8.pkg from your site and would like to install it to my unix server sun solaris 5.8. I am battling to use the pkgadd to install this package. Can you please help me in this regard as I have failed to find samba/docs/htmldocs/UNIX_INSTALL which is suppose to be instructions on how to install it on unix sun solaris. Thanking you in advance. Regards,

This is a minor question, but is there any difference between the two objects fred <- structure(1:10, dim = c(2,5)) and fred <- structure(1:10, .Dim = c(2,5)) Should I be using one rather than the other?

David's answers were correct. You are looking deep into the code when there is no reason to to so. 1. h(t|(X=x,Z=z)) = exp(Beta0 + XZBeta1) Most statisticians will tell you that this is an unwise model. The reason is that if you replace X with "X+1" the fit changes, which is almost never desirable. What if someone coded your dummy variable as 1/0 instead of 0/1 -- wouldn't
