Hi all,

I would like to suggest that all R functions/etc like:
 codes-deprecated
 grid-internal
 ns-alt
 ns-dblcolon
 ns-hooks
 ns-internals
 ns-lowlev
 ns-reflect.Rd
 tools-internal
 ts-defunct
 utils-deprecated
 utils-internal
 ... and another

i.e, function/word separate for '-'

were all substituted by
 codes_deprecated
 grid_internal
 ns_alt
 ns_dblcolon
 ns_hooks
 ns_internals
 ns_lowlev
 ns_reflect.Rd
 tools_internal
 ts_defunct
 utils_deprecated
 utils_internal
 ... and another

i.e, by '_'

Because it is impossible to make a good highlighter with the first one.

How to differentiating myValue:

varOne = 100
varTwo = 50
myValue = varOne-varTwo

from codes-deprecated, or ns-alt, for example.

One can create a variable with a minus in it by using
backquotes:

`a-b` <- 3
a <- 10
b <- 4
`a-b` + a-b

[1] 9  # 3 + 10 - 4

One other point.  The help system, i.e. ?, accommodates minus
signs like this where the last two statements below give
the same result:

library(survival)
?"survival-internal"
internal?survival

Another example is,

library(dyn)
package?dyn
