mergeSelCol: Merge selected columns out of 2 matrix or data.frames

In wrMisc: Analyze Experimental High-Throughput (Omics) Data

Merge selected columns out of 2 matrix or data.frames

Description

This function merges selected columns out of 2 matrix or data.frames. 'selCols' will be used to define columns to be used; optionally may be different for 'dat2' : define in 'supCols2'. Output-cols will get additions specified in newSuff (default '.x' and '.y')

Usage

mergeSelCol(
  dat1,
  dat2,
  selCols,
  supCols2 = NULL,
  byC = NULL,
  useAll = FALSE,
  setRownames = TRUE,
  newSuff = c(".x", ".y"),
  silent = FALSE,
  debug = FALSE,
  callFrom = NULL
)

Arguments

dat1	matrix or data.frame for fusing
dat2	matrix or data.frame for fusing
selCols	will be used to define columns to be used; optionally may be different for 'dat2' : define in 'supCols2'
supCols2	if additional column-names should be extracted form dat2
byC	(character) 'by' value used in merge
useAll	(logical) use all lines (will produce NAs when given identifyer not found un 2nd group of data)
setRownames	(logical) if TRUE, will use values of col used as 'by' as rownames instead of showing as add'l col in output
newSuff	(character) prefix (argument 'suffixes' in merge)
silent	(logical) suppress messages
debug	(logical) display additional messages for debugging
callFrom	(character) allow easier tracking of messages produced

Value

This function returns a data.frame containing the merged columns

Examples

mat1 <- matrix(c(1:7,letters[1:7],11:17), ncol=3, dimnames=list(LETTERS[1:7],c("x1","x2","x3")))
mat2 <- matrix(c(1:6,c("b","a","e","f","g","k"), 31:36),
  ncol=3, dimnames=list(LETTERS[11:16],c("y1","x2","x3")))
mergeSelCol(mat1, mat2, selC=c("x2","x3"))
