[R] R check passes code and docs that don't match

[Ross Boylan]

I have code and documentation that don't match, but R CMD check didn't
flag it.

in mspath.R
mspath <- function(formula,   # formula with  observed Markov states  
~  observation times (required)
                qmatrix,    # matrix of 1s and 0s with indices of
allowed transitions (diagonal is ignored) (required)
                misc = FALSE,
                ematrix = NULL,    # matrix of 1s and 0s with indices of
allowed misclassfications (diagonal is ignored) (required)
                inits,      # initial values of optimisation or fixed
values (required)
                subject = NULL, # optional, defaults to all the same if
not given
                covariates = NULL, # formula specifying covariates on
transition rates.
                constraint = NULL, # which intensities have covariates
on them (as in Marshall et al.)
                misccovariates = NULL, # formula specifying covariates
on misclassification probs
                miscconstraint = NULL, # which misc probs have
covariates on them
                qconstraint = NULL, # constraints on equality of
baseline intensities
                econstraint = NULL, # constraints on equality of
baseline misc probs
                covmatch = "previous",   # take the covariate value from
the previous or next observation
                initprobs = NULL,  # initial state occupancy
probabilities
                data=list(),       # optional data frame in which to
interpret variable names
                fromto = FALSE,
                fromstate, #
                tostate,   #  data required if fromto is TRUE
                timelag,   #
                death = FALSE,  # 'death' states, ie, entry time known
exactly, but unknown transient state at previous instant
                tunit = 1.0, # no longer used
                exacttimes = FALSE,
                fixedpars = NULL, # specify which parameters to fix
                stepnumerator = 1,  # maximum step size in discrete
approximation
                stepdenominator = 1,  # rational number; use integers
                do.what = 1, # 1 for likelihood, 0 for counts
                ... # options to optim
                )

in mspath.Rd
\usage{
mspath ( formula, qmatrix, misc = FALSE, ematrix, inits, subject,
      covariates = NULL, constraint = NULL, misccovariates = NULL,
      miscconstraint = NULL, qconstraint=NULL, econstraint=NULL,
      covmatch = "previous", initprobs = NULL, 
      data = list(), fromto = FALSE, fromstate, tostate, timelag,
      death = FALSE, tunit = 1.0, exacttimes = FALSE,
      fixedpars = NULL, stepsize=1.0... )
}
with corresponding \item's in the \arguments list.

Among the differences (see the end of the argument lists)
In code by not Rd: stepnumerator, stepdenominator, do.what
In Rd but not code: stepsize

Yet R CMD check says

Have I misunderstood how this is suppsed to work?  Have the previous
errors confused or voided the code/documentation test?  Is it a bug?

Using R 2.0.0-3 on Debian.
