Hi A slightly different approach xyplot(y~x|fac, groups = ifelse(age < 40,1,2), par.settings = list(strip.background = list(col = "transparent"), superpose.symbol = list(col = c("red","blue","green")), superpose.line = list(col

Re: [R] need some help with date

Thank you for the (not quite working) example. a) your '= "character"' bit is a bit anti-productive, since on the one hand you are indicating that a default value can be used (so omitting any argument is okay) yet the default value you are specifying is invalid. b) The origin argument is rare

Re: [R] need some help with date

Hi Glenn, Perhaps this will help: dateCentury<-function(x,new_century=20) { xbits<-strsplit(x,"/") long_year<-function(x,new_century) { x[3]<-ifelse(as.numeric(x[3]) <= new_century, paste(20,x[3],sep=""), paste(19,x[3],sep="")) xdate<-paste(x,collapse="/") return(xdate) } newx<-as.

[R] need some help with date

Here is a sample of the data that I am working with. Dates may go back as far as 1930’s. When I use as.Date() I noticed that any data < 12/31/68 returns as the new century. So I wrote this function below to be applied to the data which I dput below the function. If I use the function DateCen

I'm not on Windows and cannot help directly. But you might consider downloading Rstudio ( https://www.rstudio.com/ ) and running R through that. Their website should contain the info you need to get things up and running. Cheers, Bert Bert Gunter "The trouble with having an open mind is that pe

What is the R code for neuralnet for time series forecasting? This question might seem very basic but I can´t seem to get the code right. I have the data for the Pound/Euro Exchange rate

Re: [R] Adding loess lines subsetting to each panel in lattice plot

Juan: What I gave you previously was correct, but not "nice". The subscripts = TRUE argument should have been in the xyplot() call, not the pnl function. However, it is actually not explicitly needed there either, because it will default to TRUE if the panel function has a subscripts argument, whi

Re: [R] Help with non standard evaluation and require function

Hi David and Duncan, thanks for your answers! I think what is not clear to me is actually how "substitute" works. If I run require (dplyr) or require("dplyr") in the R console everything works as I expect even without the character.only=T (actually because of this I always interpreted that charac
