Re: [R] Computing growth rate

Hi Maybe you does not need if or ifelse but just divide by years difference. d2<-ddply(df1,"co_code1",transform, growth=c(NA,exp(diff(log(sales1))/diff(fyear1))- 1)*100) Cheers Petr > -Original Message- > From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of Berend >

Re: [R] Computing growth rate

Dear Mr. Barradas, Thanks a lot for pointing that. I tried that in a few steps- 1. when I evaluated d<-ddply(df1,"co_code1",transform, growth <- ifelse(diff(fyear1)==1, (exp(diff(log(df1$sales1)))-1)*100, NA)) I got the following, i.e., I was not getting the growth column automatically.

Re: [R] Computing growth rate

Wow, Mr Petr. The placing of diff(fyear1) was very clever indeed. Just to understand the steps intended by you- exp(diff(log(sales1))/diff(fyear1))- 1) = exp(((log(sales1(t)/sales1(t-1)))/(fyear1(t)-fyear(t-1)))-1) = exp(log(sales(t)/sales(t-1))^(1/(delta(fyear1-1 =

Re: [R] WaveletComp with as.POSIXct Showing Error on Date for: 2000-01-01 Format

Your code is nearly unreadable, probably because you posted in HTML instead of plain text. Plain text is the standard expected on R-help. The only apparent date/time conversion in your code is the use of as.POSIXct(). You are missing a closing quote mark after the date. If I fix that, then on

I cannot see how you get that code to run. It certainly does not on my machine and some of the manipulations don't make any sense as far as I can see. I changed variable and data.frame names so I would not have to type so much and read in the data with the "stringsAsFactors = FALSE" option. I

Hi Bailey, I may be misunderstanding what you are doing as I can't work out how you get unequal column lengths, but this may help: myval<-matrix(sample(1:365,740,TRUE),ncol=74) mydata<-as.data.frame(cbind(1950:1959,myval)) lakenames<-paste(rep(LETTERS[1:26],length.out=74),

Hello, That is a very common mistake. if() accepts only one TRUE/FALSE, for a vectorized version you need ?ifelse. Something like the following (untested). growth <- ifelse(diff(fyear1)==1, (exp(diff(log(df1$sales1)))-1)*100, NA) Hope this helps, Rui Barradas Em 15-12-2016 03:40, Brijesh

Re: [R] Computing growth rate

Berend - Unless you need the change in sales year by year, you might consider looking at each company's sales over the years and use regression or other type of trend analysis to get an overall trend... Or, if not, simply divide diff(sales) by diff(fyear1) for each company so at least you get
