This function is called automatically by HPDsummary() and also can be used separately to plot the results produced by HPDsummary() with more plotting options
1 2 |
data |
A summary table generated by HPDplot(), it is the first element in the returned list. |
xgroup |
Which factor will be used to form the x axis (for 2-way designs). |
facet |
The factor by which the plot will be split into facets (for 2-way designs). |
type |
Two types are supported: "bar" and "line" ("line" also has points). "bar" is more useful to plot fold-changes returned when HPDsummary() is run with the option 'relative=TRUE'. "line" is better for plotting actual inferred transcript abundances across factor levels; it is particularly good for time courses and other cases when multiple factor levels must be compared to each other. "bar" is good to plot log(fold-changes) relative to global control. |
x.order |
A vector giving the order of factor levels on the x-axis. If unspecified, an alphanumeric order will be used. |
whiskers |
The interval indicated by the whiskers. Default is "ci", the 95% credible interval; another option is "sd" - standard deviation of the posterior. |
genes |
Vector of gene names to plot. By default, all genes in the summary will be plotted. |
log.base |
Base of the logarithm to indicate on y-axis (does not affect plotting). |
The function invokes ggplot() functon from the ggplot2 package to plot the results either as a single panel (one-way designs) or a multi-panel (2-way designs, one panel per level of the factor specified by 'facet' argument).
A ggplot object. See http://docs.ggplot2.org/0.9.2.1/theme.html for ways to modify it, such as add text, rotate labels, change fonts, etc.
