Plot TS-matrix as a surface
Jeff and Paul, Thanks for the suggestions. Jeff's png seems to reflect what I need, will investigate/apply, and report back. PS

In the tframePlus package there is a function called tfpersp() that does this. I'm sure it can be improved, I've never been really happy with it. But you might want to compare, to be sure you are improving it. Paul Jeff Ryan wrote:
PS, I have been working on adding a chartSeries3d function to quantmod. The code isn't in place yet, but it relies on persp, and some extra manipulation to offer much better axis labeling. It is designed for xts/zoo structures in particular. The final code will work for any time-series. This should be in the next release of quantmod, but I've posted the alpha code and a .png here: http://www.quantmod.com/example/chartSeries3d HTH, Jeff R/Finance 2009: Applied Finance with R April 24, 25 2009 Chicago, IL USA http://www.RinFinance.com On Thu, Feb 26, 2009 at 8:20 AM, R at Nabble <vlanschot at yahoo.com> wrote:
Thank you Enrico. Your example helped me to solve a (embarrasingly basic) error in my code. Plots fine now. Thx again. PS Enrico Schumann wrote:
it should be helpful to give a little code example, or at least the content of the error messages that you received. the following gives me a perspective plot... require(zoo) nC <- 10 # columns nO <- 100 # observations dataM <- array(runif(nC * nO), dim=c(nO, nC)) zz <- zoo(dataM, 1:nO) persp(1:nO,1:nC,zz) regards enrico -----Urspr?ngliche Nachricht----- Von: r-sig-finance-bounces at stat.math.ethz.ch [mailto:r-sig-finance-bounces at stat.math.ethz.ch] Im Auftrag von R at Nabble Gesendet: Donnerstag, 26. Februar 2009 12:26 An: r-sig-finance at stat.math.ethz.ch Betreff: [R-SIG-Finance] [R-sig-finance] Plot TS-matrix as a surface I'd like to be able to plot a time-series matrix (i.e. first col
contains
sorted dates, rest of cols contains non-sorted data, with headings at
the
top; current format is as a zoo object) as a surface/3D chart. The function persp() is giving me errors, even if I transform data as core data, etc. Any suggestions / other functions available?
