Ivsc: Plot of intensity vs. concentration for given probes
Description
The function Ivsc plots intensity as a function of a concentration
for a given probe in the spike-in Latin square experiments. It also
peforms a non-linear data fit (using the package nls in the R-package
stats) of the experimental data using the Langmuir Isotherm:
I = I0 + Ac/(K+c)
Solid and dashed lines are best fits according to this formula.
Imax in the plot are given by Imax=I0+A, ie the asymptotic
intensity in the limit of c to infinity.
Usage
Ivsc(probe_set, probe = "NULL", outfile = "NULL")
Arguments
probe_set
Probe set number of the probe set analyzed
probe
Integer giving the probe number (if not give the probe 1 is selected)
outfile
output the plotted data to a postscript file
Warning
Some probes have an irregular behavior and the non-linear square fit
does not converge.References
