Some functions in spsUtil, spsComps and systempPipeShiny will behave differently if some SPS options are changed, but it is optional. All functions have a default value. If SPS options are not changed, they will just use the default setting. Read help files of individual functions for detail.
spsOption(opt, value = NULL, .list = NULL, empty_is_false = TRUE)
| opt | string, length 1, what option you want to get or set |
|---|---|
| value | if this is not |
| .list | list, set many SPS options together at once by passing a list to this function. |
| empty_is_false | bool, when trying to get an option value, if the
option is |
return the option value if value exists; return FALSE if the value
is empty, like NULL, NA, ""; return NULL if empty_is_false = FALSE;
see notFalsy
If value != NULL will set the option to this new value, no returns.
spsOption("test1") # get a not existing option #> [1] FALSE spsOption("test1", 1) # set the value spsOption("test1") # get the value again #> [1] 1 spsOption("test2") #> [1] FALSE spsOption("test2", empty_is_false = FALSE) #> NULL spsOption(.list = list( test1 = 123, test2 = 456 )) spsOption("test1") #> [1] 123 spsOption("test2") #> [1] 456
