Re: [R] paste0 in file path

if the files are supposed to be "1r.xlsx", "2r.xlsx" (etc) then you need to ensure there's a "/" before it. It's better to use `file.path()` to, well, build file paths since it will help account for differences between directory separators on the various operating systems out there. On Wed, Aug

[R] Number of Variables allowed in R

Hi, Can someone please tell me the maximum number of independent variables allowed in R for non linear regression. I have 50 independent variables and want to calculate non linear models to the power of 9 but R is unable to process it beyond to the power of 3 which means its taking maximum 150

Re: [R] paste0 in file path

Also, the recommended way to build file paths is to use file.path(), i.e. file.path("C:", "temp", filename) rather than paste0("C:/temp/", filename) BTW, R provides tempdir() that gives you the temporary directory that R prefers to use on your OS. So, you might want to consider using:

Hi Kai, Perhaps something like this: kmdf<-data.frame(group=rep(c("exp","cont"),each=50), time=factor(rep(1:5,20)), condition=rep(rep(c("hot","cold"),each=25),2), value=sample(100:200,100)) for(timeindx in levels(kmdf$time)) { for(condindx in levels(kmdf$condition)) {

That tmp1 - 30*60 can also be done as tmp1 - as.difftime(30, units="mins") so you don't have to remember that the internal representation of POSIXct is seconds since the start of 1970. You can choose from the following equivalent expressions. tmp1 - as.difftime(0.5, units="hours") tmp1 -

Try following this example: mydf <- data.frame(t1=c('201112312230', '201112312330')) tmp1 <- as.POSIXct(mydf$t1, format='%Y%m%d%H%M') tmp2 <- tmp1 - 30*60 mydf$t2 <- format(tmp2, '%Y%m%d%H%M') It can be made into a single line, but I used intermediate variables tmp1 and tmp2 so that it would be

Re: [R] Looping through different groups of variables in models

Kai: 1. I think that this is a very bad idea, statistically, if I understand you correctly. Generally, your model should incorporate all groups, time points, and conditions together, not individually. 2. But plotting results in "small multiples" -- aka "trellis plots" may be useful. This is done

If it doesn't do ANYTHING, you may have failed to save the file. Unless that file contains a function, in which case it isn't supposed to do anything except load the function into your global environment. But it should have thrown an error in that case, as Duncan said. On Wed, Aug 31, 2016 at

I have quantstrat installed and it works fine for me. If you're asking why the output of t(tradeStats('macross')) isn't being printed, that's because of what's described in the first paragraph in the *Details* section of help("source"): Note that running code via ‘source’ differs in a few
