variance does not equal serial covariance of lag zero?
Dear all,
Does this make any sense:
var() = cov() != acf(lag.max=0, type="covariance")?
I have daily data of IBM for May 2005, and I'm using the logarithmic return:

barplot: border color when stacked
Dear R-users,
I am using R version 2.10.1 under windows.
In a barplot, I want to mark one of the bars with a special border color.
For example:
barplot(c(3, 7, 11), border = c(NA, "red", NA))
But how to do this when the bars are stacked?
for example:
barplot(matrix(1:6, ncol=3)) # border of second bar (i.e. the one with total height = 7) should be red again, I try:
barplot(matrix(1:6,

barplot with anchored bars
Dear R list members,
How to produce barplots anchored to the x-axis (not floating
above the x-axis) with a box around?
With both following codes, the lower horizontal line of the
box is below the y = 0 line:
# first code
x <- c(1,2,3,4)
barplot(x,yaxs='i')
box()
# second code
x <- c(1,2,3,4)
op <- par(yaxs='i')
barplot(x)
box()
par(op)
The parameter yaxs='i'
