Dear all:I am having some problems to use the function "sink()". Basically I am doing a loop over two files which contain unit-root variables. Then on a loop, I extract every i element of both files to create an object called z. If z meets some requirements, then I perform a unit root test (ADF test), otherwise not. As this process is repeated several times, for each i I want to get the summary of the ADF test on a common file. For that I use the function "sink()". My code runs fine, but I do not get anything written on the text file where my results are supposed to be saved. The code is below setwd("C:\\Users\\Sergio René\\Dropbox\\R") library("urca") P1<-read.csv("2R_EQ_P_R1_500.csv") P2<-read.csv("2R_EQ_P_R2_500.csv") d<-(1:1000) sink ("ADF_results_b_1.txt") for (i in seq(d)) { z.1<-P1[i]*-1-P2[i]*-1 if (all(z.1<=0)) {r=1} else {if (all(z.1>=0)) {r=1} else {r=2}} if (r==1) {ADF<-ur.df(ts(z.1), lags=1, type='drift')} if (r==1) {summary(ADF)} } sink() Any suggestion of what I might be doing wroong?
You aren't printing anything. In a loop, you need to call print() explicitly; only the last value of an expression auto-prints.
