summarizeCols

Summarize columns (as median,mean,min,last or other methods)

Description

summarizeCols summarizes all columns of matrix (or data.frame). In case of text-columns the sorted middle (~median) will be given, unless 'maxLast', 'minLast', 'maxLast','maxAbsLast' or 'minLast' .. consider only last column of 'matr' : choose from all columns the line where (max of) last col is at min; 'medianComplete' or 'meanComplete' consideres only lines/rows where no NA occur (NA have influence other columns !)

Usage

summarizeCols(matr, meth = "median", silent = FALSE, callFrom = NULL)

Arguments

`matr`	data.frame matrix of data to be summarized by comlumn (may do different method for text and numeric comlumns)
`meth`	(character) summarization method (eg 'maxLast','minLast','maxLast','maxAbsLast','minLast','medianComplete' or 'meanComplete')
`silent`	(logical) suppress messages
`callFrom`	(character) allow easier tracking of message(s) produced

Value

vector with summary for each column

Examples

t1 <- matrix(round(runif(30,1,9)),nc=3); rownames(t1) <- letters[c(1:5,3:4,6:4)]
summarizeCols(t1,me="median")
t(sapply(by(t1,rownames(t1), function(x) x), summarizeCols,me="maxLast"))
t3 <- data.frame(ref=rep(11:15,3),tx=letters[1:15],
  matrix(round(runif(30,-3,2),1),ncol=2),stringsAsFactors=FALSE)
by(t3,t3[,1],function(x) x)
t(sapply(by(t3,t3[,1],function(x) x), summarizeCols,me="maxAbsLast"))
