Brackets: Extract or replace elements from an MPCR object.

In MPCR: Multi- And Mixed-Precision Computations

Extract or replace elements from an MPCR object.

Description

Extract or replace elements from an MPCR object using the '[', '[[', '[<-', and '[[<-' operators. When extracting values, they will be converted to double precision. However, if you update a single object, the double value will be cast down to match the precision. If the MPCR object is a matrix and you access it using the 'i' index, the operation is assumed to be performed in column-major order, or using 'i' and 'j' index.

Usage

  ## S4 method for signature 'Rcpp_MPCR'
x[i, j, drop = TRUE]
  ## S4 replacement method for signature 'Rcpp_MPCR'
x[i, j, ...] <- value
  ## S4 method for signature 'Rcpp_MPCR'
x[[i, drop = TRUE]]
  ## S4 replacement method for signature 'Rcpp_MPCR'
x[[i, ...]] <- value

Arguments

x	An MPCR object.
i	Row index or indices.
j	Column index or indices.
...	ignored.
drop	ignored.
value	A value to replace the selected elements with.

Examples

  library(MPCR)
    x <-as.MPCR(1:50,precision="single")
    ext <- x[5]
    x[5] <- 0
    x$ToMatrix(5,10)
    x[2,5]
    x[3,5] <- 100
