fit lognorm to cdf data
Dear all I am struggling to fit data which form something like CDF by lognorm. Here are my data: proc <- c(0.9, 0.84, 0.5, 0.16, 0.1) size <- c(0.144, 0.172, 0.272, 0.481, 0.583) plot(size, proc, xlim=c(0,1), ylim=c(0,1)) fit<-nls(proc~SSfpl(size, 1, 0, xmid, scal), start=list(xmid=0.2, scal=.1)) lines(seq(0,1,.01), predict(fit, newdata=data.frame(sito=seq(0,1,.01))), col=2) I tried

R and UBUNTU startup
Dear all I have 3 questions. Due to some reason I switched from Vista to Ubuntu on home PC. I was used to start with Rgui.exe. However I am not able to find it under Ubuntu and R starts as terminal (probably Rterm). Question 1. Is Rgui.exe available on linux? In Windows doc folder I can find manuals, however I did not find doc folder in Ubuntu. I found somewhere that manuals need to be

plotting the regression coefficients
Hi Petr; Thanks so much. Exactly this is what I need. I will play to change color and so on but this backbound is perfect to me. I do appreciate your help and support.

plotting the regression coefficients
Hi Petr; Thanks for your reply. It is much appreciated. A small example is given below for 4 independent and 4 dependent variables only. The values given are regression coefficients.I have looked ggplot documents before writing to you. Unfortunately, I could not figure out as my experience in ggplot is ignorable Regards.

plotting the regression coefficients
Hi Peter; The R code you provided works very well. Once again thanks so much for this. The number of variables in my data set that should appear on the y-axis is 733 and they are not numerical (for example the name of one variable is *palmitoyl-arachidonoyl-glycerol (16:0/20:4) [1]**. So, the plot looks very messy in one page. How can I make the plot to print out on multiple pages? Regards,

plotting the regression coefficients
Hi Maybe there are other ways but I would split data to several chunks e.g. in list and use for cycle to fill multipage pdf. With the toy data something like library(reshape2) library(ggplot2) temp <- melt(temp) temp.s<-split(temp, cut(1:nrow(temp), 2)) pdf("temp.pdf") for (i in 1: length(temp.s)) { p <- ggplot(temp.s[[i]], aes(x=par1, y=variable, size=abs(value),

R and UBUNTU startup
I did the same transition, facing the same issues, so I settled for installation of RKWard. This pretty much reproduces my previous experience with Tinn-R and the Rgui.

Putting 733 discrete categories on Y-axis in qqplot2 as they are
Hi Petr; I would like to get a plot with names as they are in the original file. They are chemical names and I have 733 in the my file. For example, let me give to chemical names "*2-hydroxybutyrate/2-hydroxyisobutyrate*" and "*palmitoyl-arachidonoyl-glycerol (16:0/20:4) [1]**" .So, what should I put [c(2,3,1)] part in the command:

Q1. No. Q2. What do you do? Did you follow the instructions at [1]? If you go to the top level of the R help system you should be able to open the manuals. ?help Q3. Not that I know of. If you have difficulty with R on Linux then you should focus on learning how to use Linux in general... and learn what X-Windows is. But just as with Windows, googling your problem will usually lead to stepwise

Putting 733 discrete categories on Y-axis in qqplot2 as they are
Hi When you load external file to R, character variables are converted to factors by default and alphabetically sorted. I have limited connection to internet, so I cannot find the answer, you could try it yourself. Maybe you could try not to convert vector with names to factor, which, for plotting issue is not different from factor coding. See ?read.table for details However I am not sure if it

Antwort: RE: Missing Values in Logical Expressions
Hi Petr, Hi Jim, many thanks for your help. Today I constructed a sample dataset and tested your suggestions. Everything worked OK. Then I took the code and testet on the original data. And - it worked OK this morning also. I went back to my script of Thuesday and ran it again. OK. Then I used my script of Monday and ran it.. OK. I have no idea what was wrong yesterday.

plotting the regression coefficients
Hi Petr; Thanks so much. This is great! Although last Sunday, alternatively, I have solved the problem using the following statement at the very end of the program. * ggsave('circle.pdf', p4, height = 70, width = 8, device=pdf, limitsize = F, dpi=300).* This works very well too. Asa my categorical variables are in my Y axis, my R program reorders the names on Y-axis. However, I would

Hi try str(varcompobject) to see structure of this object. You can extract parts by standard R means.

Merging RData files
Hi all, This is great. Again, here is what I need. I run two separate jobs (a.R and b.R) with results (say regression outputs) going to a.RData and b.RData. I like to put all results in one place (where I can retrieve them in one place, ab.RData). The following codes do it (I am not sure if line 2 is needed but I am happy). Thank you all. load("a.RData")
