[R] problems editing R console

[Rosa Oliveira]

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. (text edit file).

I do another setting with DP_x=3 and save, and so on.

For some reason I realize I’ve done my simulation the wrong way and I have to apply a correction, for example:

x.erro = 1.4X+erro, i.e. in the truth I could use my first X and erro values in each setting, but as it is in a .txt file I can’t use them any more. Is there a way to save the results in a  format that I can use the values? Just apply my corrections and don’t have to do the 2000 simulations for each setting again?

My problem is that the function I use takes 3 days running, and just 500 simulations :(

Best,
RO


Atenciosamente,
Rosa Oliveira
