I need to use the "terms()" function to decompose a formula.
The function seems to work for small formulas, but not for long formulas.
##############################
#The following works!
form <- cbind(log(inflowd1),log(inflowd2),log(inflowd3),
log(inflowd4)) ~ precip*I(Tmax^2)
terms(form)
#But enlarging the left-hand side of the formula causes an error!
form <- cbind(log(inflowd1),log(inflowd2),log(inflowd3),
log(inflowd4),log(inflowd5),log(inflowd6)) ~ precip*I(Tmax^2)
terms(form) # ERROR
##############################
I noticed that when the left-hand side term of the formula is
too large to be written on one line, an error occurs in terms().
However, increasing the line width by "options(width=200)" did
not solve the problem.
