map_save_ram function

Perform map using background objects with only selected markers. It saves ram memory during the procedure. It is useful if dealing with many markers in total data set.

map_save_ram(
  input.seq,
  tol = 1e-04,
  verbose = FALSE,
  rm_unlinked = FALSE,
  phase_cores = 1,
  size = NULL,
  overlap = NULL,
  parallelization.type = "PSOCK",
  max.gap = FALSE
)

Arguments

• input.seq: object of class sequence
• tol: tolerance for the C routine, i.e., the value used to evaluate convergence.
• verbose: If TRUE, print tracing information.
• rm_unlinked: When some pair of markers do not follow the linkage criteria, if TRUE one of the markers is removed and returns a vector with remaining marker numbers (useful for mds_onemap and map_avoid_unlinked functions).
• phase_cores: The number of parallel processes to use when estimating the phase of a marker. (Should be no more than 4)
• size: The center size around which an optimum is to be searched
• overlap: The desired overlap between batches
• parallelization.type: one of the supported cluster types. This should be either PSOCK (default) or FORK.
• max.gap: the marker will be removed if it have gaps higher than this defined threshold in both sides
