I am encountering difficulty with NextMethod in 0.50-a4. We created a class of groupedData objects which are data.frames with additional attributes. The most important attribute is a formula describing roles of some of the variables in the experimental design. The class of such objects ends in "groupedData", "data.frame". The print method for the groupedData class simply

The editor in R version 1.2.0 returns an error after editing a data frame that has row names. This is on a Windows 2000 system, but I've encountered the same problem under Windows 95. Here's a simple example: ------------------------------------------------------------------------------------ R : Copyright 2000, The R Development Core Team Version 1.2.0 (2000-12-15) R is free

If you use traceback() you will see it is in edit.data.frame. That tries

Hi, I use lm or loess to make smoothing. After smoothing I need "Residual Standard Error" in my script. Could you please tell me how can I get this information? Thanks,

Hi, I tried to do a multiple linear model from the example dataset Formaldehyde. However, the function lm() did not estimate the coefficient of the term carb^2. The same problem occurred with the (nlme)dataset Pixel with both function lme() and lm(). I am using the windows version of R 1.5.1 Lauri Mehtatalo The Formaldehyde example: > data(Formaldehyde) >

I would like to create a method for the generic function "with" applied to a class of fitted models. The method should do two things: 1. Substitute the name of the first argument for '.' throughout the expression 2. Evaluate the modified expression using the data argument to the fitted model as the first element of the search list. The second part is relatively easy. The

Hello R users, I have been looking through Help files and Nabble list for the answers for these simple questions, but it seems to be fruitless. 1- in a data frame with two columns, x and y, how do I get the corresponding value of x to, let's say, the minimum value of the y column (min (data$y)) ? 2- how do I solve a simple equation? Considering the equation y= exp(-x)^12, I would like to find

Greetings. Is there any way to get R to take a regression model object and draw a plot of the regression function? How about overlaying that plot over a scatterplot of the actual data?

Pasting the code right into the email is usually safest, though you DO have to post using plain text (as the Posting Guide indicates) or your code may get mangled by the automatic html format removal.

I presume by now that most everyone has heard that, starting later this quarter with Netscape 5.0's developers' release, the Netscape browser program and its source code will become freely redistributable. They didn't say it would be GPL'd (GNU Public License) but they said their source code would be available in the spirit of the GPL. Initially it bothered me that the

At present the documentation for nlm refers the reader to Dennis and Schnabel for details on the algorithms. It also states that the function is liable to change. Can anyone tell me if the current version of nlm uses only function values or if it can use gradients and Hessians when they are available? I would like to get an idea of how difficult it would be to port the development versions of

I should have saved the messages about this but I didn't. Can someone remind me of what function or object to check from within a function to determine if you are running R? I need to make some changes in code according to whether I am running it under R or under S and I would prefer to keep one source tree. Thomas Lumley: I read your web page on porting S code to R. It looks very good.

OK, Let's try this again! Here is the reproducible script; it is long because I had to copy the panel dataset here. My question is related to systemfit; I don't know how to get the result for the entire panel. #Reproducible script Empdata<- read.csv("/Users/ngwinuiazenui/Documents/UPLOADemp.csv") View(Empdata) install.packages("systemfit")

Should the F statistic be the same when using add1() on models created by lm and glm(family=gaussian)? They are in the single-degree-of-freedom case but not in the multiple-degree-of-freedom case. MASS:addterm shows the same discrepancy. It looks like the deviance (==residual sum of squares) gets divided by the number of degrees of freedom for the term twice in add1.glm. Using anova() on the
