Rows and columns of a plate

well_row() gives the row letter of each well and well_col() its column number, as factors whose levels are all the rows or all the columns of the plate, in order. Unlike well_to_row_let() and well_to_col_num(), they keep rows and columns with no wells in the data, so sorting, counting, faceting and plotting show the whole plate.

Usage

well_row(x, plate = NULL)

well_col(x, plate = NULL)

Arguments

x

Well IDs, such as "A01".

plate

The size of the plate, such as 96 or 384, or its number of rows and columns. If NULL, the plate of well() IDs is used, or else the smallest standard plate that holds all the wells.

Value

A factor the same length as x.

Examples

x <- well(c("A01", "C05"), plate = 96)
well_row(x)
#> [1] A C
#> Levels: A B C D E F G H
well_col(x)
#> [1] 1 5
#> Levels: 1 2 3 4 5 6 7 8 9 10 11 12

# Every row of the plate is counted, even those with no wells
table(well_row(x))
#> 
#> A B C D E F G H 
#> 1 0 1 0 0 0 0 0 

well_row(c("A01", "C05"), plate = 384)
#> [1] A C
#> Levels: A B C D E F G H I J K L M N O P
