Dear friends. I have trobpe with path. Below I have tried to paste a path and file name but it will not work > path <- "D:/rw0641/own/own/procedures/GFR_TIME" > path [1] "D:/rw0641/own/own/procedures/GFR_TIME" > path1 <- paste(path,"gfr.txt",sep="/") > path1 [1] "D:/rw0641/own/own/procedures/GFR_TIME/gfr.txt" -- this is good

Hi, I'm using windows xp and R 2.8.0 - I wonder what is the command to put in a script that has the same effect as when in a plot you choose menu "History" and "Recording".

Dear friends - I'm using Tinn-R in Windows and find it OK. My son is running MacOS and is just starting using R and I know nothing about MacOS and R but we seem to have difficulties in finding something similar to Tinn for MaC. What are your suggestions? Thanks a lot! Troels Ring, MD Aalborg, Denmark

Dear friends - below is a subset of a much larger material showing two ways of generating two "lines". The intention is to have the colour reflect a variable, pH, but the legend is disturbed. The little part marked "3" above the colour scale is unwelcome. Why did it appear? How could I avoid it? I'm on Windows 7, R version 3.4.1 (2017-06-30) -- "Single

Dear friends - I hope you will accept a naive question on lm: R version 3.4.1, Windows 10 I have 204 "baskets" of three types corresponding to factor F, each of size from 2 to 33 containing measurements, and need to know if the standard deviation on the measurements in each basket,sdd, is different across types, F. Plotting the observed sdd versus the sizes from 2 to 33, called

Dear friends - I'm on winXP, R 2.71 - I have with some help dveloped this multivariate normal model, which gives very plausible results in WinBUGS even without any initial values specified. However, when I then try to run the same model via the bugs function in R2WinBUGS with inits specified as inits=NULL the program stops in a dead end. So I have tried to make inits for the bugs function

Hallo all just a small question I did not find an answer in help pages. Is it possible to use identify() after plotting with plot.POSIX to label points and/or to find out some points? Thanks a lot. Best regards Petr Pikal petr.pikal at precheza.cz p.pik at volny.cz

Dear friends - I have a data.frame with "," instead of "." and found the discussion http://r.789695.n4.nabble.com/How-to-replace-all-commas-with-semicolon-in-a-string-tt4721187.html#a4721192 so copying the code of Ulrik(I hope:-)) I tried (making some data) AX <-

Dear friends - a couple of papers in PNAS (lastly:framework for making better predictions by directly estimating variables' predictivity, Lo et al PNAS 2016; 113:14277-14282) have focused interest on mapping complex traits to multiple loci spread all over the genome. I have been around on the relevant taskview(s) I hope but fail to see that the backward haplotype transmission association

Dear friends, I was drawing a circle with centrum in (1,-1) and radius 5 to show my girl that the line y=3*x+1 goes through (1,4) and (-2,-5) of the circle, but on Windows XP, R 2.20 the drawing was not good at all, and the known solutions were not shown in the graph. I guess I got it wrong? Is this use not intended ? Best wishes Troels Ring, MD Aalborg, Denmark

Dear friends, I'm probably wrong but is there anything better than bootstrap to get a confidence interval of the median from a population with unspecified distribution ? Best wishes Troels Ring, Aalborg, Denmark

When I do this (highly simplified example): plot(as.POSIXct(c("1984-01-01","1984-01-02")), c(1,2), col=2) I get a partially red (col=2) x-axis between and including the first and last tick marks. Otherwise ok. Only happens with POSIXct or POSIXlt dates. Also, POSIX dates cannot be used on the y-axis? POSIXlt gives an error, and POSIXct is unformatted. Bruce Using X11

Thank you to Peter Dalgaard, who provided help for some of this solution. It is still not ideal since the dots which are equidistant in the x-direction ideally should respect the reciprocal scale in the y-direction. op <- par("cex"= 0.7) x<-y<-NA plot(x,y,xlim=c(0,10),ylim=1/c(2000,70), axes=F) box() axis(1)

Dear friends. I wanted to reproduce a sheet of paper useful for plotting the reciprocal of some biochemical variable (creatinine) over time (Bleyer Am J Kidney Dis 34:576-578,1999). Time on X axis with units years and months. On Y axis, 1/creatinine, but with the original creatinine value indicated - to make it easier for people to use it. When using the graph, the linear decrease in 1/crea over

I hope you will forgive me this simple question on titration. I'm trying to find very small values from the algorithm below, which I believe is correctly formatted, and the constants are also correct. When SID goes over ATOT, fitted vales are much too low compared to the literature. I guess I must be using optimize in a wrong way but cannot find out how to improve it. I'm on windows, R

Hi, I'm working with objects of classes "Date","POSIXlt" and "POSIXct" and still having some Date/Time-related concepts unclear. In the documentation of "as.Date" one can find: "The 'as.Date' methods accept ... '"POSIXlt"' and '"POSIXct"'. (The last are converted to days by ignoring the time after
