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

# NOT RUN {
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"))
