Dear List, I am struggling understanding S4 classes. For example, when GLMM summary(glmmML( whatever)) outputs the following line: Estimate Std. Error DF z value Pr(>|z|) (Intercept) 0.856 0.319 45 2.68 0.0073 How do I access the Pr column? Dieter

I can't get the PERL subexpression translated to R. Following, for example, B. Ripley's http://finzi.psych.upenn.edu/R/Rhelp02a/archive/58984.html I am using sub, but it looks like an ugly substitute. Assume I want to extract the first alpha part and the first numeric part, but only if they are in sequence. Do I really have to use the sub twice, first extracting the first variable, then

Hi there, I hope I can get advice regarding the calculation of leverage values or studentized residual values of a non-linear regression model. It seems like rstudent() does not work on a nls object. Many thanks in advance! Best regards, Xingli

Dear List, I'm trying to interpret the results of the Kruskal's Non-metric Multidimensional Scaling algorithm (isoMDS, MASS package). The 'goodness of fit' is reported as "The final stress achieved (in percent)". What does this mean exactly? I've tried to google for an answer but I've not come up with a definitive answer. Regards, Dieter -- Dieter Vanderelst

Hi, my name is Dieter and this is my 1st post to the list. I''m currently using shorewall 2.2.5 on SuSE 9.2 and java 1.4.2_06. Overall everything works as expected. The problem I have occurs with previous versions of shorewall, too. Problem: When I start a java application like crushftp it takes about 2 minutes until the server is functional. If I try to interrupt the startup process

Hi Dieter, Sorry my mistake. I wanted to convert them into Decimal (not Hexadecimal). Given this string, the desired answer follows: > ascii_str <- "ORQ>IK" 79 82 81 62 73 75 > ascii_str2 <- "FDC" 70 68 67 - Gundala Viswanath Jakarta - Indonesia On Mon, Dec 22, 2008 at 5:49 PM, Dieter Menne <dieter.menne at menne-biomed.de> wrote: > Gundala

Dear List, creating factors in a given non-default orders is notoriously difficult to explain in a course. Students love the ifelse construct given below most, but I remember some comment from Martin M?chler (?) that ifelse should be banned from courses. Any better idea? Not necessarily short, easy to remember is important. Dieter data = c(1,7,10,50,70) levs =

Dear R-list, Is there a way to convert the typical long R data-format to a 1-line per subject format? I have data formatted as: Group subj condition variable 1 1 1 746.36625 2 2 1 1076.152857 1 3 1 1076.152857 2 4 1 657.4263636 1 5 1 854.1266667 2 6 1 1191.676154 1 7 1 1028.175385 1 1 2 46.36625 2 2 2 76.152857 1 3 2 76.152857 2 4 2 57.4263636 1 5 2 54.1266667 2 6 2 191.676154 1 7 2 028.175385

In the area plots below, I see 4 triangle ticks at both sides of the bar; I believe these are non-stacked values for p, but they are definitively confusing. In addition, I would like to get the order of the colors in the plot the same as in the legend, and not arranged alphabetically (the factor is ordered, don't touch my order). Hadley once mentioned an undocumented aestetics

Hi list, I'm using barplot2 form the gplots package to plot a few numbers (I want to add SD bars later). However, I would like the y-axis not to start from 0 but 500. When I add the parameters YLIM, something goes wrong. The graph is not 'cut off' at 500. Instead the bars seems to sink trough the bottom of the graph. Because its a little hard to explain, here is a self-containing

We have extracted parameters from physiological measurements by fitting SSlogis-like curves with nlsList and nlme. We presented residuals plot in a paper, but a referee argues that these cannot be included (too technical), and r-square values should be given instead to compare the goodness of fit with those of other authors. I remember that 30 years ago in my stat 101, I learned that r-square is

Hello, I'm currently trying to find a method to interpolate or smooth data that represent a trajectory in space. For example, I have an ordered (=time) set of (x,y) tuples which constitute a path in a 2D space. Is there a way using R to interpolate between these points in a way similar to spline interpolation so that I get a smooth path in space? Greetings, Dieter -- Dieter Vanderelst

Dear List, After having installed R 2.6.0/Windows 2000, my trusted command script to build and install my package fails with an error message I do not understand. I have installed a fresh copy of Rtools, and made sure that these are the first on the path. For testing, I am using a package version from an older backup where I am sure that everything else was ok.

Hi All, I have an R script that spawns output in the form of an HTML page. This is done by the R2HTML package. Now I want to run the same script using Rcmd BATCH. However, it seems that it is not possible to use R2HTML in this case. My script ends with this error message: ######################### Error in dev.print(png, file = AbsGraphFileName, width = Width, height = Height, : can only

Dear ladies and gentlemen, we are developer and producer of UPS devices. Now we would like to integrate a small UPS via USB connection to NAS systems. We heart from third party that we need a special driver for NAS systems to work fine and to display also the company name and UPS device name in the web page / software of NAS. Currently we have a UPS with USB and our own VID (0x2B2D) and PID

I read somewhere that vector graphics such as eps or dpf are more favorable than alternatives (jpeg, bmp or png) for publication because vector graphics scale properly when enlarged. However, my problem is that the file generated from a graph of fixed size is too large (in the order of 10MB) because of many data points in multiple scatterplots. Any suggestions? Thanks, Gang [[alternative HTML

we are using samba Version 1.9.18p8 and want to connect WIN-NT 3.5.1 to Samba- supportet Unix-Drives; but for any reason the password for this connection is always needed (we did the registry for enableplaintextpassword); the same connection is done well on WIN95 could you figure out, what our problem is??? thank you Klaus-Dieter Wurm (dieter.wurm@de.origini-it.com)

Hi Dieter and R community: I tried both of these three versions with ylim as suggested, none work: I am getting only single (pch = 16) not overlayed (pch =3) everytime. *vs 1* require(lattice) xyplot(Sepal.Length ~ Sepal.Width | Species , data= iris, panel= function(x, y, subscripts) { panel.xyplot(x, y, pch=16, col = "green4", ylim = c(0, 10)) panel.lmline(x, y, lty=4, col =

Dear useRs, I generated a simple image-based report using the sequence: pdf(....) plot(.....) textplot( for short texts, from gplots) dev.off() Is there an easy way to include an single pdf-page from an external file (not R generated). Note: For final reports, I know how to use Sweave, but I am looking for a quick solution with less overhead. Something like textplot() for pdf. Dieter
