.AG argi
vector or structure.  Missing values (NAs) are allowed.
.RT
vector which is the combination of all values from all
arguments to the function.
.PP
Precisely, if `argi' is a vector structure, its data values are used.
Otherwise, if `argi' is a structure, all data from all components of
`argi' is used.
In this way, `c' performs a function that is
the opposite of `split'.
.PP
Arguments that are NULL do not contribute anything to the result.
See the last example.
.EX
c(1:10,1:5,1:10)

c(1,2,3,5,7,11,13)

c(states,"Washington DC")

z <- split(data,group)  # split data by group then ..
sorted <- c(sapply(z,"sort")) #sort each component, combine result

x<-NULL; for(i in seq(10)) x <- c(x,fun(i))
