A very powerful function in CohortExplorer is the use of regular expressions to filter a table.
We can have a text box where a user may put in a regular expression. the regular expression then filters a table with concept name as follows
data[grepl(input$filterRegex, data$conceptName, ignore.case = TRUE),]
