I've looked every way I can think of for help on trellis.datasets, but nothing comes up for me. Please help me find information on what is included, and how to get at those data. Thanks. Dave Parkhurst

...ature appname: rgui.exe; Appver: 1.71.30616.0; Modname: randomforest.dll Modver: 1.70.30416.0; Offset: 00002bac I?d appreciate any help anyone can provide in tracking down why this is happening. (I successfully used rfImpute earlier on a similar dataset from another site.) Thanks. --Dave Parkhurst

...the manual, and the help system as best I can, and I don't see how to change the font size. Can it be changed from within a session, or will I have to ask the folks who installed the program on the server I use in classes to set it (assuming that can be done)? Thanks for any help. David Parkhurst

...lues with a sensible values does not effect accuracy much.? (from his report, "Manual On Setting Up, Using, And Understanding Random Forests V3.1"). I now plan to try the na.roughfix option from Liaw?s package. Thanks to Uwe Ligges and Brian Ripley for their replies to my posting. Dave Parkhurst

....25 inches numeric(0) Is my call to identify correct? The help page for indentify (from ?identify) doesn't give any examples, so I don't know what the "x" should be. I right click right on top of one of the points, then left click and select stop. Thanks for any help. Dave Parkhurst

...ector. However, when I enter n95trt <- length(byyr$cnd95[byyr$cnd95=="tr"]) n95trt the result is 68! Any ideas why this is happening, and how I can fix the miscount? (That column also contains 69 entries of "c", and (relevantly?) two NA's.) Thanks for any help. Dave Parkhurst

...variables, in about 5% of rows. I would like to have all rows included in the analysis, to the extent possible. (That seems to be possible in rpart, for example.) Is it possible to specify that rows with a few NA's should be included in the randomForest analysis? If so, how? Thanks. Dave Parkhurst

...al axis. I've looked in all the manuals, but didn't find a way to do this. I can copy the data to a spreadsheet, make the conversion there, and then move the data to R, but that's a nuisance. I'd appreciate learning whether there is a way to do this all within R. Thanks. Dave Parkhurst

...From the html help for xyplot, it appears I need to use the scales argument, but I don't fully understand the description there, about how to treat the x and y axes differently. I'd much appreciate any help. Please reply directly, as I don't subscribe to the list. Thank you. David Parkhurst

...uld be saved to a separate page, and then they could be viewed one at a time. Is there any way to do the equivalent in R? (Using splom from lattice makes the graphs too small.) Thanks for any help. (I am not subscribed to the news mailing list, so I would appreciate direct replies.) David Parkhurst

...f package ?????????????????????????????????????????????????????????????? Evidently I need to uninstall first, but I can?t figure out how. I?ve looked in the pdf manuals, in the R FAQ, and in the R for Windows FAQ, and don?t find instructions for doing so. I?d appreciate any help. Thanks. Dave Parkhurst
