  layout,
  name = "layout"
)

Arguments

layout	Character vector of length two with a mixed layout (two opposing triangles).
name	Name of the column that should contain the layouts.

Value

The input data frame with a new column added, showing in which triangle each value would be in a mixed layout.

Examples

# Make long format symmetric data
long_df <- data.frame(rw = rep(letters[1:4], 4),
                      cl = rep(letters[1:4], each = 4),
                      val = 0)

long_df <- add_mixed_layout(long_df, rw, cl, val,
                            layout = c("topleft", "bottomright"))

head(long_df)
