SMOLR_TO_PPP: Convert localizations to point pattern for spatstat package

In maartenpaul/SMoLR: Single Molecule Localization Microscopy visualization and analysis in R

Description

A function to convert localization data coordinates to point patterns for the spatstat package. Input can be separate vectors, data.frame or a list of data.frames.

Usage

SMOLR_TO_PPP(x, y, xlim, ylim, marks, shape)

Arguments

x	X coordinates in nm, or a data.frame or list of data.frames with localization data.
y	Y coordinates in nm
xlim	Vector with the upper and lower limit of x coordinates
ylim	Vector with the upper and lower limit of y coordinates
marks	Vector to indictate different types/channels of the coordinates. If list or data.frame is used as input the channel column will be used for the marks.
shape	Shape of the point pattern, either a rectangle ("rect") or circle ("circle"). Default is "rect".

Value

Returns a spatstat ppp object, or a list of ppp objects.
