I haven't used R in a couple of years, and now am trying something as simple as importing a csv file and am running into problems right away. * mydata <- read.csv (Wordata1.csv, sep="") Error in read.table(file = file, header = header, sep = sep, quote = quote, : object 'Wordata1.csv' not found *I've tried in both as as read.csv and read.table and still get the

I am working with a list of dates and I would like to replace each date with the one that comes after, ie. 1/1/07 will become 1/5/07, 1/5/07 will become 1/7/07, etc. The number of days between my dates always varies, so I can't just increase each one by 5 days or so. Does anyone know of a way I can do this in R? thank you [[alternative HTML version deleted]]

I'm trying to convert data from character to numeric. I've imported data as a csv file, I'm assuming that the import is a database - are all the columns in a database considered "vectors" and that they can be operated on individually Therefore I've tried the following mydata <- as.numeric(mydata$apples) when i then look at mydata again the named column is still

I'm running the following code numbers <- 1:50 for (i in 1:50) assign(paste("model",numbers[i]),i)<-(lm(temp$Overall.Scaled.Score~temp$raw.score)) where I want R to create 50 different models-1:50, but get the following error message "target of assignment expands to non-language object". I've tried it with

I'm trying to create a colored map that would show the number of students per state. My data frame consists of two columns - state and count. I'm using the following code library(maps) map("usa") library(plotrix) state.col<-color.scale(gre$count,0,0,c(0,1)) map("state",fill=TRUE,col=state.col) I'm getting a map, but the values are not being mapped to correct

I'm trying to create a fairly basic map using R. What i want to get is the map of the country with circles representing a count of students in each state. What I've done so far is as following - map("state") symbols(data1$count,circles=log(data1$count)*3,fg=col,bg=col,add=T,inches=F) this gives me the map of the country, but one that's not populated by my counts. Does

I've created a number of models using lm and now want to pick one with the smallest standard error or the smallest RSS, I can get a list of RSS using anova function, but is the any way I can then select one with the smallest RSS from the list? [[alternative HTML version deleted]]

I suppose that, as expected, it's invalidated less often this way. Given that it's generally stateless, does this really represent a cost savings?  -Hal > > Thank you, > Alina > > > On Mon, Feb 10,

Yes, this is odd.

Thank you Michael, Curves for each level of the factor sounds very interesting, Do you have a suggestion how to plot them? Thank you!

I am trying to overlay a data frame with lat and longitude(which refer to zip codes) on the map of US that I get by using map ("states"). Is there anyway to do this or do I have to resort to using maptools? thank you [[alternative HTML version deleted]]

Dear Alina If I understand you correctly you cannot just have a single predicted curve but one for each level of your factor.

Hi Hal, Yes, the "internal" caches AA would be valid as long as the IR is not mutated. Are you suggesting keeping them? It's possible, but it will be very tricky to ensure they are cleared at the right times and they will likely be prone to adding hidden bugs. I don't have strong indications currently that keeping such information would be useful by other users, other than

Great, thanks! Are you planning on just talking about these things with slides?

Instead, we have an IR reference: the unoptimized IR. Mmmmm, thinking more about it, yes we could compile the IR two times and use the unoptimized one as a reference.
