We will try our best to offer additional help for learning R in this forum. Questions and discussions are warmly welcome!
par(mar = rep(0, 4))
for (i in 1:360) {
plot(1, ann = F, type = "n", axes = F)
text(1, 1, "Welcome", srt = i,
col = rainbow(360)[i], cex = 7 * i/360)
Sys.sleep(0.01)
}

Thanks!
Another silly demo to show how xlim works:
par(mar = rep(0, 4))
for (i in 1:200) {
plot(1, xlim = c(0, 2), ann = F, type = "n", axes = F, xaxs = "i")
text(2 - i/200 * 3, 1, "happy_rabbit -___-//", col = topo.colors(200)[i],
cex = 3)
Sys.sleep(0.02)
}

The effect of the code running in Windows is much better than in Linux. I tried a lot but still can not find any way to avoid the flicker when drawing repeatedly in Linux.

Yes I also noticed this phenomenon long ago. Is that something called "double-buffering" which R does not support?

I am trying to do a cross tabulation of two variables. Sex and the answer to a survey question. Both variables are factors. This is easy to do using the table function. The problem is that these respondents have weights. Table does not have an option to put in weights. Any ideas? Thanks! I'm in ST 579 so relatively new to R so explanations where you explain why I should do what I should would be appreciated.
