## Heatmap with more sensible behavior using heatmap.plus

### Description

Heatmap with more sensible behavior using heatmap.plus

### Usage

    TCGAvisualize_Heatmap(data, col.metadata, row.metadata,
      col.colors = NULL, row.colors = NULL, show_column_names = FALSE,
      show_row_names = FALSE, cluster_rows = FALSE,
      cluster_columns = FALSE, sortCol, extrems = NULL,
      rownames.size = 12, title = NULL, color.levels = NULL,
      values.label = NULL, filename = "heatmap.pdf", width = 10,
      height = 10, type = "expression", scale = "none",
      heatmap.legend.color.bar = "continuous")

### Arguments

`data` | The object to with the heatmap data (expression, methylation)
`col.metadata` | Metadata for the columns (samples). It should have on of the following columns: barcode (28 characters) column to match with the samples. It will also work with "bcr_patient_barcode"(12 chars),"patient"(12 chars),"sample"(16 chars) columns but as one patient might have more than one sample, this coul lead to errors in the annotation. The code will throw a warning in case two samples are from the same patient.
`row.metadata` | Metadata for the rows genes (expression) or probes (methylation)
`col.colors` | A list of names colors
`row.colors` | A list of named colors
`show_column_names` | Show column names names? Dafault: FALSE
`show_row_names` | Show row names? Dafault: FALSE
`cluster_rows` | Cluster rows ? Dafault: FALSE
`cluster_columns` | Cluster columns ? Dafault: FALSE
`sortCol` | Name of the column to be used to sort the columns
`extrems` | Extrems of colors (vector of 3 values)
`rownames.size` | Rownames size
`title` | Title of the plot
`color.levels` | A vector with the colors (low level, middle level, high level)
`values.label` | Text of the levels in the heatmap
`filename` | Filename to save the heatmap. Default: heatmap.png
`width` | figure width
`height` | figure height
`type` | Select the colors of the heatmap values. Possible values are "expression" (default), "methylation"
`scale` | Use z-score to make the heatmap? If we want to show differences between genes, it is good to make Z-score by samples (force each sample to have zero mean and standard deviation=1). If we want to show differences between samples, it is good to make Z-score by genes (force each gene to have zero mean and standard deviation=1). Possibilities: "row", "col". Default "none"
`heatmap.legend.color.bar` | Heatmap legends values type. Options: "continuous", "disctrete

### Value

Heatmap plotted in the device
