Re: [R] gap.plot fails to plot tick labels on y-axis

Hi Ludo, The good news is that it was easy. The bad news is that it was my fault. I hadn't tried labeling the axes with something other than numbers. At about line 109 in the source code, this line: show.labels<-c(ytics[littletics],yticlab[bigtics]) should read: show.labels<-c(yticlab[li

Hello, What do you want to sample? Rows? With or without replacement? You need to give us more information on what you want. Start by seeing the help page for ?sample Hope this helps, Rui Barradas   Citando MARYAM : > Dear mr/madam > I have 3 matrix with 20 rows and 3 columns like this: I w

Re: [R] Use SQL in R environment

If you're wanting to retrieve data from external databases (I vaguely recall that is what SAS's proc sql does), then start by looking at the DBI package, which provides support for ROracle, RMySQL, and several more. There is also RODBC. -- Don MacQueen Lawrence Livermore National Laboratory 700

[R] Survival::coxph (clogit), survConcordance vs. summary(fit) concordance

Hi, I'm running conditional logistic regression with survival::clogit. I have "1-1 case-control" data, i.e., there is 1 case and 1 control in each strata. Model: fit <- clogit(resp ~ x1 + x2, strata(ID), cluster(site), method ="efron", data = dat) Where resp is 1's and 0's, and x1 and x2 are both

FAQ 7.31 maybe. (Unless special software is used) Only a finite number of numbers can be represented exactly on a computer. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom C

[R] gap.plot fails to plot tick labels on y-axis

Dear all, I'm using gap.plot(..) (plotrix-3-5-11) to make a plot containing a broken axis. It seems in some cases that gap.plot() does not plot the proper tick labels at the y-axis. Case in question is when I specify tick labels for all ticks, on both y-ranges (ones below and one above the gap). W

[R] Adjust Richards model with nlme

Hello everyone, I have tried to adjust the non linear Richards growth model with this script: richards <- function(x,beta1,beta2,beta3,beta4) beta1*(1-beta2*exp(-x*beta3))^beta4 richards <- deriv(~beta1*(1-beta2*exp(-x*beta3))^beta4,c("beta1","beta2","beta3","beta4"),function(x,beta1,beta2,b
