Generate a CATMAID URL for a node or connector

Simple method for generating a CATMAID URL pointing to a particular skeleton node or connector

simple_catmaid_url(dfrow, skid, sid0 = 5, zoom = 0, conn = FALSE,
  treenode_id = NULL, xyz_columns = c("x", "y", "z"))

Arguments

dfrow	Required; a single data frame row containing columns of xyz coordinates and (optionally) `connector_id` with CATMAID coordinates and the connector ID
skid	Required; the skid of the active skeleton
sid0	The ID of the desired stack mirror on your CATMAID server. Found by generating a URL within CATMAID and picking out the `sid0` param. Defaults to 5.
zoom	The desired zoom level (`s0` parameter) of the URL. Defaults to 0.
conn	Whether or not to specify an active connector ID in the URL. Defaults to `FALSE`.
treenode_id	A specific treenode ID to set as the active node. Useful if you are generating URLs for nodes postsynaptic to a particular skeleton. Will be ignored if `conn` is set to `TRUE`.
xyz_columns	A character vector specifying the names of the columns containing x, y, and z coordinates. Defaults to `c("x", "y", "z")`.

A character string with the CATMAID URL.

Requires the catmaid.server option to be set in .Rprofile
