Rosa, Why not just re-load the .txt file (which I imagine be a data frame) and then edit?
See: http://www.inside-r.org/r-doc/utils/read.table *I would imagine something along the lines:* simulation_results <- read.table("path_to_text_file_of_simulation") #Double check the parameters on the function documentation, I don't know how your data looks like, specially header and column separator. *For doing something like: * x.erro = 1.4X+erro *you would just need to use:* simulation_results$x.erro <- 1.4*simulation_results$X + simulation$erro *then save the simulation_results variable again.* Also see... http://stackoverflow.com/questions/8345759/how-to-save-a-data-frame-in-r Carlos Andrade http://carlosandrade.co On Sun, Jun 7, 2015 at 12:58 PM, Rosa Oliveira <rosit...@gmail.com> wrote: > Dear Mark, > > > I’ll try to explain better. > > Imagine I write: > > library(foreign) > library(nlme) > > set.seed(1000) > n.sample<-10000 #sample size > M <- 5 > DP_x <- 2 > x <- rnorm(n.sample,M,DP_x) > p <- pnorm(-3+x) > y <- rbinom(n.sample,1,p) > dp_erro <- 0.01 > erro <- rnorm(n.sample,0,dp_erro) > x.erro <- x+erro > > but with a function, with 2000 simulations. > I save my “output” and I get X.erro in a .txt file.
