precise_heatmap.RdThis function will run heatmap on the output of precise_dist or a list of distance matrices.
precise_heatmap(data, method = "complete", type = "ggplot2", diagonal = NULL, parallel = FALSE, verbose = FALSE)
| data | A square, numeric dataframe, matrix or tibble. |
|---|---|
| verbose | TRUE or FALSE. Should the function tell you what is happening internally? |
| max_iter | A positive integer for the number of iterations. See details. |
| perplexity | A positive integer that loosely equates to the number of nearest neighboors. See details. |
| theta | A positive numeric value between 0-1 that toggles between exact heatmap and Barnes-Hut heatmap. See details. |
| suffix | A string to be used as the suffix for the output distance name. |
| file | NULL or the absolute path to save the results as an RData file. |
| cores | An integer value equal to 1 or greater for the number of computer cores to use. |
A list of heatmap results, which can be viewed with trellis_heatmap.
toggles between two versions of heatmap. If theta = 0.0, a modified version of heatmap is run,
otherwise if theta > 0.0, heatmap is run.
