  x,
  rows,
  cols,
  values,
  labels = NULL,
  annot_rows = NULL,
  annot_cols = NULL,
  facet_rows = NULL,
  facet_cols = NULL,
  ...
)

Value

A ggplot2 object with the heatmap. If return_data is TRUE, plotting data is returned as well.

Arguments

x

Data frame containing data to plot.

rows, cols, values

Columns to use as rows, columns, and cell values.

labels

Column to use for cell labels. NULL (default) for no labels.

annot_rows, annot_cols

Columns to use for row and column annotations.

facet_rows, facet_cols

Columns to use for row/column facet memberships.

Examples

# Basic example
set.seed(123)
hm_in <- data.frame(row = rep(letters[1:10], each = 5),
                    col = rep(LETTERS[1:5], 10),
                    val = rnorm(50))
gghm_tidy(hm_in, row, col, val)

# Annotation and clustering
# Add annotation by giving names of columns in the data
hm_in$row_annot1 <- rep(1:10, each = 5)
hm_in$row_annot2 <- rep(10:1, each = 5)
hm_in$col_annot <- rep(letters[1:5], 10)
# Columns are given using 'tidy' selection
# so they can be unquoted, quoted, from variables (with !! notation) or indices
gghm_tidy(hm_in, row, col, val,
          annot_rows = c(row_annot1, row_annot2),
          annot_cols = col_annot,
          cluster_rows = TRUE,
          cluster_cols = TRUE)

# Add cell labels
hm_in$lab <- 1:50
gghm_tidy(hm_in, row, col, val,
          labels = lab, cell_label_col = "white")
