mergeSelCol

Merge selected columns out of 2 matrix or data.frames

Description

mergeSelCol 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"),
  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`)
`callFrom`	(character) allow easier tracking of message(s) produced

Value

data.frame

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"))
