Use changeInput() to change an input's selected values. Values may be
selected using regular expression pattern matching or exact matches, see
fixed.
changeInput(id, pattern, fixed = FALSE, invert = FALSE, reset = TRUE,
propagate = FALSE, session = getDefaultReactiveDomain())A character string specifying the id of an input.
A character string specifying a regular expression, if fixed
is FALSE, values which match the expression will be selected. If fixed
is TRUE, a character vector of one or more values specifying exact values
to select.
One of TRUE or FALSE specifying if pattern is interpreted
as a regular expression or a vector of character literals, defaults to
FALSE.
One of TRUE or FALSE specifying how values are matched,
if TRUE values which do not match pattern will be selected, defaults
to FALSE.
One of TRUE or FALSE indicating how to handle any currently
selected values, if TRUE the current selection is dropped before
selecting new values, defaults to TRUE.
One of TRUE or FALSE specifying if the value change
causes a re-evaluation of dependent reactives and observers, defaults to
FALSE.
A reactive context, defaults to getDefaultReactiveDomain().
