Please use a descriptive subject and not tag onto a prior thread
for new topics.
Assuming the first row is time 1 and the second row is time 2 and
so on try:
diff(log(P))

help with table partition
Hi,
I have a test_table where the dim is 62220 by 73 (row by col)
I would like to partition the rows into 170 equal parts (170 tables
where each is of dim 366 by 73), and rearrange them horizontally. The
source codes I have:
for (i in 1:170) {
c = cbind(c,test_table[(367*i+1):(367*(i+1)),2:73]);
}
Unfortunately, using for loop and cbind for a table of this size

hist, lines, rug
Hello,
I'm trying to plot a historgram with a density plot superimposed:
hist(x, seq(-1, 1, by = 0.1), prob = T, col = "blue")
lines(density(x, bw = 0.1))
rug(x)
I don't want to add rug(x) but the histogram will not be plotted unless
rug(x) is there. It does not work if the "hist" line alone is present.
Can you help?
Thanks,
Kim
