[R] replacing period with a space

Dear R-ers! I have x as a variable in a data frame x. x-data.frame(x=c(aa.bb,cc.dd.ee)) x$x-as.character(x$x) x I am sorry for such a simple question - but how can I replace all periods in x$x with spaces? sub('.', ' ', x$x) - removes all letters to the left of each period... Thanks a lot for

Re: [R] replacing period with a space

As you've discovered, the . means something special in regular expressions (and R's version of them). You need to escape it with \\: x-data.frame(x=c(aa.bb,cc.dd.ee)) x$x-as.character(x$x) x x 1aa.bb 2 cc.dd.ee sub(\\., , x$x) [1] aa bbcc dd.ee gsub(\\., , x$x) [1] aa bb

Thanks, Chuck's answer is the closest to what i want (gives the same result as cumprod()) ...but using this function seems actually slower than the loop (is it normal ?): a1-runif(10) cadd-function(x) Reduce(*, x, accumulate = TRUE) looop-function(a1){ j-length(a1) for(i in 2:j){

[R] How to specify an ARMA(1, [1,4]) model?

Hi, I'm trying to model an ARMA(1,[1,4]), i.e. I want only lags 1 and 4 of the Moving Average part. It's the '[1,4]' part that is giving me a problem. I've tried different arma's and arima's in different packages, namely: packages tseries, fArma, FinTS, timeSeries, TSA, Zelig, ds1, forecast

Re: [R] replacing period with a space

Here is one more that works: gsub(., ,Start.Time, fixed = TRUE) fixed = TRUE really helps in a lot of instances for removing specific characters without accidently angering the regular expression gods. Enjoy. --- On Tue, 10/13/09, Dimitri Liakhovitski ld7...@gmail.com wrote: From:
