R-listers: I am summarizing input I got on a recent query about creating stacked, colored line plots in xyplot. The only input I got regarding xyplot was to use the polygon() command, but this seemed to require some awkward data manipulation. In contrast, I got several snippets of functional code

Re: [R] Options for viewing / using results from lm

Hello, >Why do you think it is better done in another program? Keeping it in R saves you from the exporting, which you say you are having trouble with. I think it might be better for viewing capabilities. If I had columns of residuals right next to each other I could spot differences amongst loca

Re: [R] How to convert backslash to slash?

Except it's a bit tricker because: s <- "C:\foo\bar" print(s) You'd need to work with encodeString( "C:\foo\bar") but that won't work in general: "c:\xjobs" "c:\" "c:\help" Hadley On Tue, Sep 23, 2008 at 3:00 PM, Shengqiao Li <[EMAIL PROTECTED]> wrote: > > How to use sub, gsub, etc. to repla

Re: [R] Options for viewing / using results from lm

You can do things like this pseudocode: > fit1 <- lm( y ~ x1, data=mydata ) > fit2 <- lm( y ~ x2, data=mydata ) > fit3 <- lm( y ~ x1*x2, data=mydata ) ... > mydata$r1 <- resid(fit1) > mydata$r2 <- resid(fit2) > mydata$r3 <- resid(fit3) Or > mydata <- cbind(mydata, r1=resid(fit1), r2=resid(fit2)

[R] Proper power computation for one-sided binomial tests.

Hi, I trying to determine the best way to compute the power for a one-sample one-sided binomial test. Specifically I need to sample a population of individuals and ask whether a sample rate of 0% is compatable with a minimum threshold of 3% and how many samples are needed. I have made use of powe

[R] Contional

Hi All, I'm having trouble selecting rows to delete, that i can't seem to overcome. Below is some sample data, i am trying to dedup the data based on each user, and simultaneously the timestamp (at the side i have highlighted expected row to be removed) I've looked at the lag function but can't

Re: [R] Options for viewing / using results from lm

Greg, Thanks for the pseudocode and cbind suggestions I think these should be quite helpful. What package is the function 'view' in? As for exporting elsewhere, basically I would to have the values of residuals saved in a spreadsheet in addition to any visualizations created within R. Thanks, M Ju

Michael test[!duplicated(paste(test$timestamp, test$user_id)),] should remove the second (and subsequent) occurrences of duplicates. Your example suggests you don't always want to keep the first occurrence, but the rule which determines which occurrence you want to keep is not obvious to me. HT

One way of modeling this is to use discrete event simulation since you want some randomness to the time it takes trucks to travel and therefore be available for the next load. I have used this to model various aspects of loading and routing trucks. On Tue, Sep 23, 2008 at 4:58 PM, senne <[EMAIL P
