need 95% confidence interval bands on cubic extrapolation
Dear R experts:
I need to get this plot, but also with 95% confidence interval bands:
hour <- c(1, 2, 3, 4, 5, 6)
millivolts <- c(3.5, 5, 7.5, 13, 40, 58)
plot(hour, millivolts, xlim=c(1,10), ylim=c(0,1000))
pm <- lm(millivolts ~ poly(hour, 3))
curve(predict(pm, data.frame(hour=x)), add=TRUE)
How can the 95% confidence interval band curves be plotted too?
Sincerely,
James Salsman
P.S. I know I shoul...

a revival in upstream NUT.
Another part was more technical, a sort of stalemate in design: many
mapping tables in NUT involve data conversions (e.g. date formats,
temperature units, integer milliVolts to floating-point Volts, text labels
for numeric enum values, etc.) for data transfers from a device or writes
back to it. In the current C codebase (*-mib.c, *-hid.c) there are helper
methods to which we can point from the tables. An equivalent for DMF, with
mappings conveyed by text files, involv...

Configuring TDM400 in Australia
Hi, all
I have installed TDM400 with 1 FXS and 1 FXP ports.
Now I am goig through documentation on how to configure it.
It mentions 3 protocols: Loopstart, Groundstart and Koolstart. Which one do
I use?
Can someone send me sample zaptel.conf file for Australia? This will save me
some time and will be used as a working example.
Thanks,
Rudolf

Ha! I got several on and off list requests for details, so I'll give a
bunch of details here and then maybe I can move this to a wiki page others
can help edit.
WARNING! WARNING! WARNING!
Be careful! My implementation required opening up high power components,
and dealing with 120VAC mains power and high currents on 12VDC. If you
decide to tackle any of this yourself, you need to understand

Supporting a DIY UPS with minimal effort but maximum gain
Hello,
I found out about NUT just days ago while searching for a solution for my
home setup. After some digging through the interwebs, I come to you with
questions.
I'm putting together a DIY 12V UPS, very similar to what this guy did:

Looks very great, thanks for writing this! I gather you'd port this to the
Wiki page you've started, too?
