convertWellCoordinates {cellHTS2} | R Documentation

## Converts different well identifiers

### Description

Converts between different ways of specifying well coordinates. For example, "B02" <-> c("B", "02") <-> 26.

### Usage

    convertWellCoordinates(x, pdim, type="384")

### Arguments

`x` | either: a character vector with alphanumeric well identifiers (e.g. `B03`); or an `nx2` character matrix whose first column contains letters and whose second column contains numbers; or an integer vector with position identifiers for wells within a plate (e.g. 27).
`pdim` | a vector of length 2 with names `nrow` and `ncol` giving the number of rows and columns in a plate. E.g. 'c(nrow=16, ncol=24)' for 384-well plates.
`type` | an alternative way of specifying `pdim`. Supported are the values "24" for `c(nrow=4, ncol=6)`, "96" for `c(nrow= 8, ncol=12)` "384" for `c(nrow=16, ncol=24)`.

### Value

A list with elements: `letnum`, with the alphanumeric well identifiers; `let.num`, with the alphanumeric well identifiers giving as a pair c(LETTER, 2-digits); `num`, with the integer position of the well within a plate.

### Examples

        pd <- c("nrow"=8L, "ncol"=12L) # 96-well plate
        w <- sample(prod(pd), 3L)
        wpos <- convertWellCoordinates(w, pd)
        wpos
