LogMap-class: A Logical Map

In SeuratObject: Data Structures for Single Cell Data

A Logical Map

Description

A simple container for storing mappings of values using logical matrices. Keeps track of which values (rows) are present in which observations (columns). LogMap objects can be created with LogMap(); queries can be performed with [[ and observations can be added or removed with [[<-

Usage

LogMap(y)

## S4 method for signature 'LogMap,character,missing'
x[[i, j, ...]]

## S4 method for signature 'LogMap,missing,missing'
x[[i, j, ...]]

## S4 method for signature 'LogMap,'NULL',missing'
x[[i, j, ...]]

## S4 replacement method for signature 'LogMap,character,missing,character'
x[[i, j, ...]] <- value

## S4 replacement method for signature 'LogMap,character,missing,integer'
x[[i, j, ...]] <- value

## S4 replacement method for signature 'LogMap,character,missing,'NULL''
x[[i, j, ...]] <- value

## S4 replacement method for signature 'LogMap,character,missing,numeric'
x[[i, j, ...]] <- value

Arguments

y	A character vector
x	A LogMap object
i	A character vector of length 1, or NULL
j	Not used
...	Ignored
value	A character or integer vector of values to record in the map for i, or NULL to remove the record for i

Value

LogMap: A new LogMap object with zero columns and length(x = x) rows; rownames are set to x

[[: if i is a character vector, the rownames that are mapped to i; otherwise the rownames of x

[[<-: If value is NULL, then x without the observations for i; otherwise, x with a new column for i recording a TRUE for all values present in value

Slots

.Data

A logical matrix with at least one row

Examples

# Create a LogMap
map <- LogMap(letters[1:10])
map

# Get the names of values in the LogMap
map[[NULL]]
rownames(map)

# Add an observation to the LogMap
map[['obs']] <- c(1, 3, 7)
map[['entry']] <- c(2, 7, 10)
map

# Get the names of observations in the LogMap
colnames(map)

# Fetch an observation from the LogMap
map[['obs']]

# Get the full logical matrix
map[[]]

# Remove an observation from the LogMap
map[['obs']] <- NULL
map[['entry']] <- NULL
map
