I was wondering if it's possible to have an output datatable in a R Shiny app with Excel-like filtering. More specifically, I'm looking for a way to either select all the elements in a given column but exclude a few (imagine we have 100 different values in a column and we want to exclude just 2 of them) or unselect all the values and only choose a few. In Excel we have those little square boxes that allow us to tick/untick a specific value in a column. Now, I know we have the shiny selectInput with the MULTIPLE parameter:
selectInput("select_max_mdy_rtg", label = "Max Mdy Rtg",
choices = list("Aaa" = "aaa", "Aa1"="aa1", "Aa2"="aa2", "Aa3" = "aa3", "A1"="a1","A2"="a2","A3"="a3",
"Baa1"="baa1","Baa2"="baa2","Baa3"="baa3","Ba1"="ba1","Ba2"="ba2","Ba3"="ba3","B1"="b1","B2"="b2","B3"="b3",
"Caa1"="caa1","Caa2"="caa2","Caa3"="caa3","Ca"="ca","C"="c","D"="d","NR/WR/NA"="na"),
selected = 'aaa', MULTIPLE=T)
However, this doesn't allow me to exclude just a few values. I have seen a similar question Shiny datatable filter box but the solution proposed there doesn't allow to select all the values and exclude just a few of them, plus I don't necessarily need the filters at the bottom of the table. I would need precisely what we can do in excel when filtering values in a given column. Thoughts on this? Thanks
