I did a search on Bugzilla for "plot.ts" and didn't find anything on
this issue. I tried to sign up for Bugzilla to report it, but my e-mail
address didn't pass your "syntax checking" for a legal e-mail address.
The bug is easily reproducible on my machine as follows:
## start
# generate some data
y <- arima.sim(list(), 150)
# this will definitely dispatch to a ".ts" method
class(y)[1] == 'ts'
# compare and note that `cex = 0.5` has no effect
plot(y, type = 'b', pch = 16)
plot(y, type = 'b', pch = 16, cex = 0.5)
# it works if `y` is coerced back to a regular vector
plot(as.numeric(y), type = 'b', pch = 16, cex = 0.5)
# another way to see the issue
plot.ts(y, type = 'b', pch = 16, cex = 0.5)
plot.default(y, type = 'b', pch = 16, cex = 0.5)
## end
Skimming through source code for `plot.ts`, it seems like the `cex`
argument is being "eaten" by a `...` somewhere without being properly
passed to `plot.default`.
