Hi all, Sorry for what might be a trivial issue. However, I am
completely flummoxed!
I'm making a filled contour plot for a publication. It's a continuous
wavelet transform should anybody care. The problem I'm having is
correctly demarking the ticks on the y axis. I have a matrix that has
100 columns. Every 10th column represents a power of 2. So:
col[10] <- 2
col[20] <- 4
col[30] <- 8
and so on until col[100] <- 2^10
I'm having trouble scaling my plot accordingly. Can anybody help? I
imagine that one uses the plot.axes argument but I'm having trouble
figuring out how to do it. The matrix is already a log scale so the
ticks and numbers are evenly spaced by 10.
Thanks in advance, Andy
Example:
junk.mat <- matrix(rnorm(12800), 128, 100)
xYears <- 1:nrow(junk.mat)
yPeriod <- 1:ncol(junk.mat)
filled.contour(xYears,
yPeriod,
junk.mat,
color = terrain.colors)
#? plot.axes = { axis(2, seq(??))}

Hi all, Does any one know if there is Kalman Filter code or library in R.
