weighting in nls
I'm fitting nonlinear functions to some growth data but I'm getting radically different results in R to another program (Prism). Furthermore the values from the other program give a better fit and seem more realistic. I think there is a problem with the results from the r nls function. The differences only occur with weighted data so I think I'm making a mistake in the weighting.

Protocol for answering basic questions
I have been following the discussions on 'Reasons not to answer very basic questions in a straightforward way' with interest as someone who is also new to R and has had similar experiences. As such it with sadness that I note that most seem to agree with the present approach to the responses to basic questions. I must thank those respondants to my own questions who have been helpful, but

deleting specified NA values
I have a data set of about 10000 records which was compiled from several smaller data sets using SPSS. During compilation 88 false records were accidentally introduced which comprise all NA values. I want to delete these records but not other missing data. The functions na.exclude and na.omit seem to remove all values of NA? How can I delete just the relevant NA's? . i.e. I want to delete

Cross-compilers for 2.7.0
Hello, Am I right in thinking the cross-compilations tools, kindly maintained by Prof Ripley, are still waiting to be updated for 2.7.0? Thanks, Iago -- Iago Mosqueira Cefas Systems Modelling Pakefield Rd. Lowestoft NR33 0HT U.K. +44 (0)1502 558003

S4 generic for lowess
...39; and 'o' are present in the argument list but are really defined inside the function itself. I suppose I can safely ignore this warning, and the new methods seems to work fine, but I was curious to know if there is a better way to deal with this.

Loadhistory problems
History files saved using nFile Save History do not open when using File Load History. I notice that when they are saved they do not seem to have a file extension and there is no option to chose an extension. Is this a problem. Other than this it seems so simple that I can't see what the problem is. I've tried using loadhistory and savehistory with the same problems. The syntax guide

Nonlinear weighted least squares estimation
Hi there, I'm trying to fit a growth curve to some data and need to use a weighted least squares estimator to account for heteroscedasticity in the data. A weights argument is available in nls that would appear to be appropriate for this purpose, but it is listed as 'not yet implemented'. Is there another package which could implement this procedure?

Automatic differentiation in R
Hi I recently gave a presentation about Automatic Differentiation (AD) and R at the Eighth Euro AD Workshop in Oxford (17/07/09). The presentation was intended as a general introduction to R and the desire for a generic AD interface for R. During the presentation I emphasised the need and the high level of interest that the R community has in developing such an interface and that input from the

Basic Q on coercing factors in data frames to numeric
Hi there, I'm running R 2.0.0 on Windows 95. I'm trying to coerce a column of factors within a data frame to numeric. This is not a problem with a vector, but I can't find a way to index a column within a data frame to achieve this. All the examples from 'An introduction to R', 'S-plus 6 programmers guide', etc, use simple vectors. I'm sure I'm missing
