Description Usage Arguments Details Author(s) See Also Examples

This functions plots the posterior probability of being expressed versus expressions level for a particular gene cross many cells.

1	zyPlot(name, sc2p.obj, group.name, log2scale = TRUE, showname = TRUE, annotation = NULL)

`name`	Character for the name of a gene.
`sc2p.obj`	An object of sc2pSet, result from the eset2Phase function.
`group.name`	Character for the name of factors indicating the experimental conditions. This has to be the name of a column in pData(sc2p.obj) data frame.
`log2scale`	Logical to indicate whether to plot expression level in log2 scale. Default is TRUE.
`showname`	Logical to indicate whether to show the name of genes as the tile of the figure.
`annotation`	WHAT IS THIS??

In general, the probability of being expressed for a gene is higher when the expression level is high. However, the probability is also affected by other cell- and gene-specific factors. For example, cell with higher total depth will have greater values for all genes belong to that cell. Genes with higher average expression levels will have higher background, thus the threshold for expression will be higher than genes with lower average expression.

This function provides visualization of the expression status and expression level.
