I have created a tabPanel and want to give the chance to filter by different variables (e.g., show All, gender (male or female), gaming frequency (never, sometimes, often). Giving a filter possibility on the right side of the table.
The tabPanel alone is working fine, however, I do not know how to add the select Input filter (a) multiple variables as well as b) used the output$data for output$mytable.
Gender <- c(2, 2, 2, 1, 2, 2, 1, 1, 1, 2, 2, 1, 2, 1, 1, 1, 2, 1, 2, 1) # 1 male, 2 female
Gaming_freq <- c(2, 3, 3, 3, 6, 4, 5, 5, 3, 5, 6, 5, 3, 3, 3, 2, 5, 6, 6, 3) # 2 = less than once a month, 3= once a month, 4 = once a week, 5 = more than once a week, 6 = daily

You can filter your data and wrap it in a reactive element, so you can later use it for any subsequent output plots/tables. You can read more about working with reactive expressions on Rstudio website.
Here as a demo, I get an input on the 'Gender', for further filtering the data out (I've used radio buttons but you can use your widget of choice: slider, select button, etc.)
radioButtons("gender", "filter for gender",
choices = c("One" = '1',
"Two" = '2')),
Then in the server, I use this input to filter the data based on the gender, and wrap it up in a reactive element:
filteredData <- reactive({
tempDataTable <- d %>% dplyr::filter(Gender==input$gender)
tempDataTable
})
Next you can use this reactive element containing your filtered data for generating output tables:
output$mytable1 <- DT::renderDataTable({
d <- filteredData()
DT::datatable(round(d[,3:5], digits = 3), options = list(lengthMenu = c(5, 30, 50, 90), pageLength = 10, bFilter=0))
})
You can use similar strategy to add additional filters or features, find the entire demo ui+server code here:
