setBlock: setBlock

In charles-plessy/smallCAGEqc: ad-hoc QC functions for shallow-sequenced test CAGE libraries

Description

Define properties for a rectangular block in a 96- or 384-well plate.

Usage

setBlock(plate, block, what, value)

Arguments

plate	A data frame representing a multiwell plate ("long format").
block	Coordinates of a rectangular block, or a vector of coordinates.
what	A column name in the plate data frame.
value	The value to insert or update with.

Details

Update a data frame representing a multiwell plate, by setting a given value for all wells in a block or a list of blocks defined by the well coordinates of their upper-left and bottom-right corners.

Examples

## Not run: 
plate <- setBlock(plate, "A01~C04", "dNTP", 0.5)

# Same with magrittr
plate %<>% setBlock("A01~C04", "dNTP", 0.5)

# Chained updates with magrittr
plate %<>%
  setBlock("A01~C04", "dNTP", 0.5) %>%
  setBlock("A01~C04", "Mg",   3.0)

## End(Not run)

p <- data.frame(Well = platetools::num_to_well(1:96))
p$Row <- sub("..$", "", p$Well) %>% factor
p$Col <- sub("^.",  "", p$Well) %>% as.numeric %>% factor

p %>% setBlock("A01~B02", "dNTP", 0.5) %>% head
p %>% setBlock(c("A01~B02", "D01~D02"), "dNTP", 0.5) %>% head
