melt_tornado: Reshape tornado to long format
In teunbrand/tornadoplot: Tornado Plot

Description Usage Arguments Value Note See Also Examples

The melt_tornado emulates for the TornadoExperiment class what the melt() function does in the reshape2 package. It converts the data to long format, which is the format of choice in the tidyverse family of packages.

1	melt_tornado(tornado, assay_name = assayNames(tornado))

`tornado`	A TornadoExperiment object.
`assay_name`	A `character(1)`: one of the assay names.

A data.frame with prod(dim(tornado)) rows.

For plotting purposes, the prep_tornado() function does a more efficient job than melt_tornado().

Other tornado utilities: flatten_features(), norm_tornado(), sort_tornado()

# Melt a tornado
tor <- dummy_tornado()
# Reshaping to long format
df  <- melt_tornado(tor)

# Building a tornado plot from scratch
require(ggplot2)
ggplot(df, aes(position, feature_nr)) +
  geom_raster(aes(fill = value)) +
  facet_grid(feature_set ~ sample_name)
