'colors.jm' displays the codes for colors in R.
ARGUMENTS:
'start.num = the number of the first color to be displayed.  The

'compare.files' takes 2 path specifications, 'd1' and 'd2',
as inputs, and returns a list with 3 components: (i) files
in 'd1' that are not in 'd2'; (ii) file in 'd2' that are not
in 'd1'; and files that are in both 'd1' and 'd2'.
If 'Size==TRUE', then it also returns a dataframe of files
for which the filename and size are identical, and another
dataframe of files for which the filename but not the size are
identical.
if 'Time==TRUE', then it also returns a dataframe of files
for which the filename and date/time of last modification
are identical, and another dataframe of files for which the
filename but not the date/time of last modification are
identical.

computerID function computerID function returns "x220" (alias for "SPARSEGREY") when running R on the X220 laptop; it returns "uhouse" when running R on the UHouse computer; it returns "jcthinkpad" when running R on JC's Thinkpad; it returns "unknown" when it is running on any other computer.

'conflicts.jm' is based on the 'conflicts' function - it returns the names of objects that occur in multiple locations on the search path.  Unlike 'conflicts', it also identifies the files or packages that contain these objects.

ARGUMENTS

'where' names the locations on the search path to be searched for duplicated object names.  'where' defaults to 'search()'.

If 'detail = TRUE' (default), the locations of duplicated object names are returned; if FALSE, only the names of duplicated objects are returned.

If 'all.nm = FALSE' (default), only duplicated object names that do not begin with '.' are returned; if 'TRUE', then duplicated object names that begin with '.' are returned along with all others.

If 'filename.only = TRUE' (default), then labels "file:" and "package:" are omitted.  If 'filename.only = FALSE, then these labels are included.
