Documentation for SLiM function outputMSSample, which is a method of the SLiM class Subpopulation. Note that the R function is a stub, it does not do anything in R (except bring up this documentation). It will only do anything useful when used inside a slim_block function further nested in a slim_script function call, where it will be translated into valid SLiM code as part of a full SLiM script.

outputMSSample(
  sampleSize,
  replace,
  requestedSex,
  filePath,
  append,
  filterMonomorphic
)

Arguments

sampleSize

An object of type integer. Must be of length 1 (a singleton). See details for description.

replace

An object of type logical. Must be of length 1 (a singleton). The default value is T. See details for description.

requestedSex

An object of type string. Must be of length 1 (a singleton). The default value is "*". See details for description.

filePath

An object of type null or string. Must be of length 1 (a singleton). The default value is NULL. See details for description.

append

An object of type logical. Must be of length 1 (a singleton). The default value is F. See details for description.

filterMonomorphic

An object of type logical. Must be of length 1 (a singleton). The default value is F. See details for description.

Value

An object of type void.

Details

Documentation for this function can be found in the official SLiM manual: page 740.

Output a random sample from the subpopulation in MS format (see section 27.2.2 for output format details). Positions in the output will span the interval [0,1]. A sample of genomes (not entire individuals, note) of size sampleSize from the subpopulation will be output. The sample may be done either with or without replacement, as specified by replace; the default is to sample with replacement. A particular sex of individuals may be requested for the sample, for simulations in which sex is enabled, by passing "M" or "F" for requestedSex; passing "*", the default, indicates that genomes from individuals should be selected randomly, without respect to sex. If the sampling options provided by this method are not adequate, see the outputMS() method of Genome for a more flexible low-level option. If the optional parameter filePath is NULL (the default), output will be sent to Eidos's output stream (see section 4.2.1). Otherwise, output will be sent to the filesystem path specified by filePath, overwriting that file if append if F, or appending to the end of it if append is T. If filterMonomorphic is F (the default), all mutations that are present in the sample will be included in the output. This means that some mutations may be included that are actually monomorphic within the sample (i.e., that exist in every sampled genome, and are thus apparently fixed). These may be filtered out with filterMonomorphic = T if desired; note that this option means that some mutations that do exist in the sampled genomes might not be included in the output, simply because they exist in every sampled genome. See outputSample() and outputVCFSample() for other output formats. Output is generally done in a late() event, so that the output reflects the state of the simulation at the end of a tick.
