msmsply(mspct, .fun, ..., .parallel = FALSE, .paropts = NULL)

msdply(mspct, .fun, ..., idx = NULL, col.names = NULL,
  .parallel = FALSE, .paropts = NULL)

mslply(mspct, .fun, ..., .parallel = FALSE, .paropts = NULL)

msaply(mspct, .fun, ..., .drop = TRUE, .parallel = FALSE,
  .paropts = NULL)

Arguments

mspct

an object of class generic_mspct or a derived class

.fun

a function

...

other arguments passed to .fun

.parallel

if TRUE, apply function in parallel, using parallel backend provided by foreach

.paropts

a list of additional options passed into the foreach function when parallel computation is enabled. This is important if (for example) your code relies on external data or packages: use the .export and .packages arguments to supply them so that all cluster nodes have the correct environment set up for computing.

idx

character Name of the column with the names of the members of the collection of spectra.

col.names

character Names to be used for data columns.

.drop

should extra dimensions of length 1 in the output be dropped, simplifying the output. Defaults to TRUE

Value

a collection of spectra in the case of msmsply

a data frame in the case of msdply

a list in the case of mslply

an vector in the case of msaply
