Displaying a URL saved in a dataframe in a label

Hello again and thanks for your prompt response.

I have tried adding the html tags as per your example

addPolygons(data = project_2004, # sixth group
              fillColor = ~pal(meanSIMDrank6),
              weight = 2,
              opacity = 1,
              color = "white",
              dashArray = "3",
              fillOpacity = 0.7,
              highlight = highlightOptions(
                weight = 2,
                color = "#666",
                dashArray = "",
                fillOpacity = 0.7,
                bringToFront = TRUE),
              group = "SIMD2004",
              label=~paste(project_2004$lad17nm,
                           round(project_2004$meanSIMDrank6),
                           <"a href =\project_2004$councilProfile\, target=\"_blank\">Population</a>"),
              labelOptions = labelOptions(textsize = "12px",
                                          direction = "auto")) %>%

But I'm getting the following errors:
