Hi, I upgraded to version 1.2.1 and now the up/down arrows for recalling commands no longer works. Is there a work around for this? > version _ platform sparc-sun-solaris2.7 arch sparc os solaris2.7 system sparc, solaris2.7 status major 1 minor 2.1 year

I need to completely remove row.names from a dataframe. Are there other ways to remove them (and not anything else) besides: mydataframe<-data.frame(mydataframe, row.names=NULL) I realize that this doesn't really remove the row.names; it merely replaces the current row.names vector with the numbers 1..nrow (in quotes). ===================== Dr. Marc R.

Hi All, What I would like to do is the following: a) fit a probability function to a measured data set. This would be user specified, e.g., normal, lognormal, etc. and then b) take the probability function and plot it with the histogram of the measured data set. This function would be displayed as a smooth curve. This would involve "re-sizing" the probability function to match

This example, x<-1:10 y1<-x y2<-x+2 plot(x,y1,pch=21,ylim=range(c(y1,y2)),type="o",lty="solid",bg="white") points(x,y2,pch=22,type="o",lty="dashed",bg="white") legend(7,3,legend=c("y1","y2"),pch=c(21,22),lty=c("solid","dashed"),bg="white") works if I use pch = one of 21-25. But

This might be an easy question. I tried to catch the results of nls, but to no avail. For example, if I try to fit a modle y~A*x*x+B*x+C nls will print out what A, B, and C, but how can I store these numbers to a different variable so that I can make use of them? I tried to "unclass" the result of nls, but couldn't see any of the parameters. Y C Tao

Howdy! I have a problem that's similar to one discussed earlier on the list: When not in xterm all the backspace and cursor-movements and stuff are working well. Only when I start R in an xterm window backspace appears as ^H and so on. What can I do?

Hi! When checking validity of a model for a large number of experimental data I thought it to be interesting to check the information provided by the summary method programmatically. Still I could not find out which method to use to get to those data. Example (not my real world data, but to show the point): [BEGIN] > DNase1 <- subset(DNase, Run == 1) > fm1DNase1 <- nls(density ~

Hi All, Two quick questions. 1) I am using write.table to output data.frames to ascii files, e.g., test <- data.frame(rnorm(2)) write.table(test,file="output") "rnorm.2." "1" -0.718560808193286 "2" -1.07965693020656 Is it possible to output the data without the first column, i.e., "rnorm.2." -0.718560808193286 -1.07965693020656 2) Is

Hi, I would like to have four plots plotted in the one figure and under each plot the caption (a) ... (d). Using mtext I can get so far: > plot(1:10, exp(1:10), log = "y", xlab = "xlab") > mtext("(a)",side=1,line=4.5) > plot(1:10, exp(1:10), log = "y", xlab = "xlab") > mtext("(b)",side=1,line=4.5) > plot(1:10,

Hi All, Is the Levenberg-Marquardt algorithm available in R. This method combines the steepest descent algorithm and Newton's method.

Hello I followed the example in page 59, chapter 11 of the 'Introduction to R' manual. I entered my own x,y data. I used the least squares. My function has 5 parameters: p[1], p[2], p[3], p[4], p[5]. I plotted the x-y data. Then I used lines(spline(xfit,yfit)) to overlay best curves on the data while changing the parameters. My question is how do I calculate the residual sum of squares.

Hello! I work with : R : Copyright 2006, The R Foundation for Statistical Computing Version 2.3.1 (2006-06-01) On Windows XP Professional (Version 2002) SP2. At this moment I use the function "nls" combined with a selfStar model (SSmicmen, related to Michaelis-Menten equation, and provided by the "stats" package). When I realise the following operation (cf. p 59 of the

Dermot MacSweeney pointed out to me that after my "fix" of legend(), points were no longer coming out placed in the middle of the lines, but at the right-hand edge. It turns out that naively swapping the order of point-drawing and line-drawing also messes up the bookkeeping that legend() does on the current x-location. Here's my patch, which fixes that bookkeeping (and incidentally

Thank you very much for the example. I think interactively I could get something. But my obstacle is to write an R script that processes my set of data automatically. My difficulty is to extract the information that appears on the screen, when R is operated interactively, from a scripts. Let me go over some steps to make sure I am doing things right. Assume my data have been read into the matrix

Hi All, As a follow-on from the mail below, it is possible to have boxplots based on means and variance for more than one input, i.e., bxp(input1,input2,....)
