init.data {phyloarray} | R Documentation |
Read the important fields of the several raw data-objects and store them in a new object (with class "phyloarray"). This function also reads the temperatures from the headers.
init.data2()
The function returns an object of class phyloarray
. It is a list
with values R (red signal), G (green signal), Rb (red background
signal), Gb (green background signal), Rsd (standard deviation of red
signal) and Gsd (standard deviation of green signal). The standard
deviation values are used to mark bad spots (based on sd/signal). The
list contains also X- and Y-values of the spots (to calculate
background, if necessary) and the ID's of the probes.
Each field R, G, Rb, Gb, Rsd and Gsd is a datamatrix with in the rows
the values for the different probes and in the columns the different
temperatures. To a larger extent, the columns may be other factors to
(such as time-related values), but they are designed to be used for
making melting curves and analysis on the melting curves.
Since there is a function init.data
in sma
, this function has
been calles init.data2
. It is largely the same function, but some
fields are added to make the phylogenetic analysis of melting curves
more easy.
Some examples of basic handling of an object of class phyloarray is in
the help-file Phylodata
