masplit
Split a matrix of delimited strings.
masplit( myMat, delim = ",", count = 0L, record = 1L, sort = 1L, decreasing = 1L )
myMat |
a matrix of delimited strings (e.g., "7,2"). |
delim |
character that delimits values. |
count |
return the count of delimited records. |
record |
which (1-based) record to return. |
sort |
should the records be sorted prior to selecting the element (0,1)? |
decreasing |
should the values be sorted decreasing (1) or increasing (0)? |
Split a matrix of delimited strings that represent numerics into numerics. The parameter count returns a matrix of integers indicating how many delimited records exist in each element. This is intended to help if you do not know how many records are in each element particularly if there is a mixture of numbers of records. The parameter record indicates which record to return (first, second, third, ...). The parameter sort indicates whether the records in each element should be sorted (1) or not (0) prior to selection. When sorting has been selected decreasing indicates if the sorting should be performed in a decreasing (1) or increasing (0) manner prior to selection.
A numeric matrix
set.seed(999)
x1 <- round(rnorm(n=9, mean=10, sd=2))
x2 <- round(rnorm(n=9, mean=20, sd=2))
ad <- matrix(paste(x1, x2, sep=","), nrow=3, ncol=3)
colnames(ad) <- paste('Sample', 1:3, sep="_")
rownames(ad) <- paste('Variant', 1:3, sep="_")
ad[1,1] <- "9,23,12"
is.na(ad[3,1]) <- TRUE
ad
masplit(ad, count = 1)
masplit(ad, sort = 0)
masplit(ad, sort = 0, record = 2)
masplit(ad, sort = 0, record = 3)
masplit(ad, sort = 1, decreasing = 0)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
