I receive warnings() that make debugging difficult. I have two

I think you've posted this to the wrong list. Maybe R-help instead?
1. In this part of my script, I want my script to return “Inf”. I receive the
following warning.
In min(df12.[df12.[, 7] <= 0, 1]) :
no non-missing arguments to min; returning Inf
Is there are command to eliminate the warning message?
You can add another value and suppress the message:
min(c()) gives the warning, min(c(), 2) will give 2. You'll need to
find some value that you can distinguish from a real minimum...
Sorry, no comment on your other question.

2. I use the following legend that returns a plot that I am happy with and no
errors:
legend("topright",
title = "",
legend = c(
expression("Predictions:"),
bquote(bar(u)[A] == .(u.a)),
bquote(bar(u)[D] == .(u.d))
),
cex = c(0.75,0.75,0.75)
)
At the same time, I receive the following warnings:
warnings()
Warning messages:
1: In if (xc < 0) text.width <- -text.width :
the condition has length > 1 and only the first element will be used
2: In strheight(legend, units = "user", cex = cex)/yc :

3: In w0 * rep.int(0:(ncol - 1), rep.int(n.legpercol, ncol)) :

9: In if (xc < 0) text.width <- -text.width :

If I remove “bquote” from “legend,” no warnings are produced.
By the way, “xc,” “yextra”, and other variable listed are not part of my
script. I have no idea what to do with the warning information.
Is there a better way to write my “legend” code?
Thanks,
Paul
