I am running your OS (though it would also be nice if you reported the
results of sessionInfo() ). In any case, this worked for me on R
2.12.0 (i386-pc-mingw32):
for(i in 1:6) {Sys.sleep(3); print(i); flush.console()}
For your problem, I imagine something like (though untested because no data):
for (i in 1:23194) {
dat.stat[i,c(2:8)]<-quantile(dat.bat[BL==block[i],2],prob=c(0,0.025,0.25,0.5,0.75,0.975,1))
print(i)
flush.console()
}
