plates: creats a plate layout scaffold

In olobiolo/acutils: Aleks Chlebowski's Utility Functions

Description

Create an empty plate in the form of a data frame.

Create and examine plate layouts.

Usage

empty.plate(wells = 384)

pmatrix(x, rows, cols)

Arguments

wells	number of wells in layout
x	layout object: data frame, list or atomic vector
rows, cols	backup for supplying non-standard matrix dimensions

Details

empty.plate creates a scaffold: a data frame with well, row and column variables. More variables can be added to is with a series of ifelse statements. pmatrix can then conveniently display all features in matrix form.

Value

a data frame or a NULL if the format is not supported

Functions

• empty.plate: create a layout scaffold

• pmatrix: quick peek at a layout matrix

Scaffold

The scaffold is a data frame with three columns: well, row, and column. Rows and columns are numbered as the given format requires, e.g. a 384-well plate has rows A through P and columns 1 through 24.

Formats

This function is only so smart. It has some hard coded formats that it will recognize, otherwise it returns a NULL

• * full plates of 6, 12, 24, 48, 96 and 384 wells,

• * partial 384 plates:

  • 336 wells: only rows B through O

  • 228 wells: only rows C through N

Feature display

Each feature of the plate is represented as a matrix corresponding to the plate dimensions. The format is determined based on the well number.

pmatrix accepts a single feature (vector) or a whole layout object (a data frame) or a list.

The well number is rigidly determined based on the dimensions of x then a wrapper for matrix() is created and applied to all columns
