Re: [R] plot.window: need finite 'ylim' values
Hi Mike, This looks to me as though the error is not being generated by plot, but by a method specific to the package, maybe something with a name like plot.chart_Series, that is barfing on a vector of NA values.

Re: [R] plot.window: need finite 'ylim' values
You are using a function whose help page says it is "highly experimental". In
such cases it is probably better to contact the package maintainer with a
feature request. The DESCRIPTION file says contact should be through one of

I've set minimum <- 0 maximum <- 1 The error persists. But besides that, passing 'type="n"' to plot would only make sense when called once an I know there are only NAs to plot. Since I want to generate many charts in a loop I would have to check for plotable data first to decide if 'type="n"' should be passed. As a workaround for now I do something similar. I check if the range to be plotted is completely NA. If so I manipulate one of those observations (which can only be 0, 1 or NA) to an "illegal" value of 0.5.

Re: [R] plot.window: need finite 'ylim' values
Hi Mike,
Try this:
plot (chart_Series (sample.xts[,1], subset=subset, TA=ta),
type="n",ylim=c(minimum,maximum))
where minimum and maximum are the extremes of the plot if there were
any valid values.

[R] plot.window: need finite 'ylim' values
Dear R users,
I have already asked this in r-sig-finance (not getting a solution)
but it seems to be plot-related anyway.
I like to plot several financial charts to files with an identical
layout according to "indicators" so the charts can be browsed
quickly.
quantmod::chart_Series is a function to plot a financially-related
chart in the upper part and zero or more indicators below. Normally
these indicators would be assigned defined values at least in some
part of the subset/window to be plotted, which is fine for plot. But
if all observations are NA chart_Series throws
Error in plot.window(c(1, 31), c(NaN, NaN)) : need finite 'ylim' values
While this outcome for plot/plot.window may be intended for most
applications it is undesirable here. Getting a blank subwindow here is
intended if the indicator is completely NA (at least in the subset to
be plotted).
This post
https://stat.ethz.ch/pipermail/r-sig-finance/2020q3/015000.html
suggests to generate the plot object with chart_Series and then to
explicitly set x$Env$ylim[[4]] before plotting - without success.
Can I tell plot/plot.window to ignore such errors and simply generate
an empty region instead?
Thanks
Mike
My minimal reproducible:
library(quantmod)
my_plot_function <- function () {
data (sample_matrix)
sample.xts <- as.xts (sample_matrix[1:50,'Close'], dateFormat="POSIXct")
sample.xts <- cbind (sample.xts, NA)
sample.xts[50,2] <- 0
colnames (sample.xts) <- c('Close', 'Indicator')
# Indicator
ta <- list ("add_TA(sample.xts[,2])")
# In the range to be plotted ta is completely NA
subset <- '2007-01-10::2007-01-30'
plot (chart_Series (sample.xts[,1], subset=subset, TA=ta))
}
