character vector x
.
%strim%
is an alias for %<>%
.
Usage
x %s><% ss
x %s<>% ss
x %sget% ss
x %strim% ss
Arguments

a character vector. |
ss |
a vector of length 2, or a matrix with 2 columns with |
Details
These operators serve as a way to provide straight-forward string sub-setting.

.

.
The x %s<>% ss
