readmulti.nts: Read landmark data from multiple nts files
Description
Read a list of names for several *.nts files to obtain
landmark coordinates for a set of specimens
Usage
readmulti.nts(filelist)
Arguments
filelist
A list of names for the *.nts files to be
read by the function. The names in the list require
quotes (").
Value
Function returns a (p x k x n) array, where p is the
number of landmark points, k is the number of landmark
dimensions (2 or 3), and n is the number of specimens.
The third dimension of this array contains names for each
specimen, which are obtained from the original file
names.
Details
This function reads a list containing the names of
multiple *.nts files, where each contains the landmark
coordinates for a single specimen. For these files, the
number of variables (columns) of the data matrix will
equal the number of dimensions of the landmark data (k=2
or 3). When the function is called a dialog box is
opened, from which the user may select multiple *.nts
files. These are then read and concatenated into a single
matrix for all specimens.
