filterConnectionsForPlotting.Rd
This helper function provides an easy and flexible way to retain particular connections for plotting and discard all others. Note that this filtering is only
relevant and applicable for the function `visualizeGRN()` and ignored anywhere else. This makes it possible to visualize only specific TF regulons or to plot only
connections that fulfill particular filter criteria. Due to the flexibility of the implementation by allowing arbitrary filters that are passed directly to
dplyr::filter
, users can visually investigate the eGRN, which is particularly useful when the eGRNs is large and has many connections.
filterConnectionsForPlotting(GRN, plotAll = TRUE, ..., forceRerun = FALSE)
Object of class GRN
TRUE
or FALSE
. Default TRUE
. Should all connections be included for plotting?
If set to TRUE
, all connections are marked for plotting and everything else is ignored. This resets any previous setting.
If set FALSE
, the filter expressions (if any) are used to determine which connection to plot
An arbitrary set of arguments that is used directly, without modification, as input for dplyr::filter and therefore has to be valid expression that dplyr::filter understands.
The filtering is based on the all.filtered
table as stored in GRN@connections$all.filtered$`0`
. Thus, the specific filters can be completely
arbitrary for ultimate flexibility and must only adhere to the column names and types as defined in GRN@connections$all.filtered$`0`
. See the examples also for what you can do.
TRUE
or FALSE
. Default FALSE
. Force execution, even if the GRN object already contains the result. Overwrites the old results.
An updated GRN
object, with added data from this function.
