problem with normalizePath()
The packages "readxl" and "haven" (and possibly others) no longer access files on shared network drives. The problem appears to be in the normalizePath() function. The file can be read from a local drive or by functions that don't call normalizePath(). The error thrown is
Error: path[1]="\\Hzndhhsvf2/data/OCPH/EPI/BHSDM/Group/17.xls": The system cannot find the

problem with normalizePath()
I found this as well. At our institution, our home directories are on
network shares that are mapped to local drives. The default, it appears, is
to set the location for libraries (etc) to the network share name
(//computer//share/director/a/b/user) rather than the local drive mapping
(H:/). Given the issue with dir.create(), this means it's impossible to
install packages (since it tries to

recode() function results in logical output, not factor output
Dear R Users:
I have race-ethnicity groups identified in the factor variable Ethnic_G.
I need to collapse Ethnic_G into a new variable with only two factors, 1 (White, non-Hispanic) and 2 (Minority).
As seen in the code and output below, the recoded race-ethnicity variable is put into logical format, not factor format.
I've used library(car) and the package was updated.

Binning or grouping data
Newbie here. Many apologies in advance for using the incorrect lingo. I'm
new to statistics and VERY new to R.
I'm attempting to "group" or "bin" data together in order to analyze them as
a combined group rather than as discrete set. I'll provide a simple example
of the data for illustrative purposes.

Complicated For Loop (to me)
Hello,
I'm trying to run a loop that will subset my data into specific sets by

Overlaying maps
I'm having difficulty overlaying maps when writing to a file graphics
device. My command sequence has the structure
plot(map1)
par(new = T)
plot(map2)
On the screen device, it works fine. When I attempt something like
png(file = "map.png")
plot(map1)
par(new = T)
plot(map2)
dev.off()
only the last map appears, the previous ones having been cleared. Can
someone clarify?
Thanks,
