Re: [R] Printing vector

Hello, Maybe something like the following is what you want. I have added an extra argument 'fill' to allow to choose what to print in the end. It's default value is "" making the entire matrix elements characters but it can be NA or 0. print0 <- function(x, len = 10, digits = 2, fill = ""){

Re: [R] Printing vector

Dear All: Below is what I meant. Procedure print0 allows me to print a vector of length 53 in four rows of 10 plus 1 row of 3 (Ido not like the NA). This is silly. I am hoping that there is a candid way to print the matrix. Thank you. Steven Yen === n<-53; x<-runif(n); # x<-round(x,2) print0

[R] Printing vector

Is there a convenient way to print a vector into rows of a specified column length? What I need is to print in the old FORTRAN format, viz., format(10F8.2) which would print, for instance, a vector of 25 into two rows of 10 plus an incomplete row of 5. I managed to write a procedure for that ta

Re: [R] Capturing positive and negative changes using R

Thank you much, this was very helpful. Jim’s and Daniel’s code was spot on. Indeed, as Jeff Newmiller pointed out, one of the problems was that I assumed that R could recognise decimals - I did as Richard O’Keefe suggested and the problem was gone. Thanks again! Faradj > On 21 Jul 2019, a

Re: [R] Capturing positive and negative changes using R

Here is one more option using the ave() function. Using Jim's data and naming convention fkdf$X1_change <- ave(fkdf[,'X1'], fkdf$Country, FUN=function(x) c(0,diff(x))) fkdf$X2_change <- ave(fkdf[,'X2'], fkdf$Country, FUN=function(x) c(0,diff(x))) hope this is helpful, Dan -- Daniel Nordlun
