[R] question about the tisPlot function in package tis
List, I am using the 'tisPlot' function in Jeff Hallman's excellent tis package and was hoping that someone could spare me from having to dig into the code of his 'tisPlot' function. So far as I can tell, the preferred method of controlling the plotting of the x-axis is using the 'xTickFreq' and 'xTickSkip' options. Unfortunately, the where the data ends up on the resultant plot is not invariant to this choice, as indicated in the documentation of the 'xTickFreq' option. Has anyone adjusted the frequency of their x-axis label using this package before? I imagine that there must be a better way of doing what I am trying to accomplish, but if not, does anyone have a suggestion on how to work around this without digging into the function itself? ## an example library(tis) strt <- ti(2101, "monthly") dat <- tis(runif(9*12 - 1), start=strt) # ends in 11/2008 par(mfrow=c(2,1)) tisPlot(dat, xTickFreq="monthly", xTickSkip=6) # graph ends in 11/2008, but looks to start some time in late 1999 tisPlot(dat, xTickFreq="monthly", xTickSkip=12) # graph looks to end around 3/2009 ## end TIA, Kyle ___ Research Associate, Macroeconomics Federal Reserve Bank of San Francisco [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] question about the tisPlot function in package tis
The development version of zoo has a tis to zoo conversion function
that would allow you to plot your data using plot.zoo and xplot.zoo
in which case you can use classic graphics axis function (for plot.zoo)
or lattice facilities (with xyplot.zoo):
source("http://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/*checkout*/pkg/R/as.zoo.tis.R?rev=524&root=zoo";)
z <- as.zoo(dat, class = "yearmon")
plot(dat)
xyplot(dat)
There are many examples at ?plot.zoo and ?xyplot.zoo and
in the three zoo vignettes.

Re: [R] question about the tisPlot function in package tis
Sorry that should have been:
library(zoo)
z <- as.zoo(dat, class = "yearmon")
plot(z)
xyplot(z)

The documentation for xTickFreq > says: xTickFreq: a string like the ones returned by 'tifName'. This argument and 'xTickSkip' jointly specify locations for labeled x axis ticks as follow: (i) find the 'ti''s of the given frequency that correspond to 'xAxisMin' and 'xAxisMax', then (ii) including those as endpoints, generate a sequence of every 'xTickSkip''th 'ti' between them. Two special strings can also be given. "none" means no labelled tick marks, while "auto" tries (not always successfully) to come up with reasonable tick locations automatically. "auto" also overrides any 'xTickSkip' setting. The default is "auto". which does not indicate that your data points are moved. At any rate, please try my suggestion above, which gives a pretty nice axis for your time range.
