manipulating text to generate different formulas to use in nls()
...g on that
number.
For example, when there are two sinusoids:
> nls( y ~ mu + A1 * cos(2*pi*f1*x - P1) + A2 * cos(2*pi*f2*x - P2), data = some.xy.data,
start = list( mu=some.value0, A1=some.value1, P1=some.value2, A2=some.value3,
P2=some.value4, f1=some.value5, f2=some.value6 ) )
Adding a third sinusoid, the model and the starting parameters needed become:
> nls( y ~ mu + A1 * cos(2*pi*f1*x - P1) + A2 * cos(2*pi*f2*x - P2) + A3 * cos(2*pi*f3*x - P3),
data = some.xy.data, start = list( mu=some.value0, A1=some.value1,
P1=...

# lookup items from a CSV file

# colname1, colname2, colname3,... (must be first line)
# key1, value2, value3,...
# key2, value4, value5
#
# lookup_csv(filename,key1,colname3) will then return value3
#
# TODO:
# proper CSV parsing (e.g. quoting)
# regexp on the value?
# return a supplied default if row not found?
