The goal of blob is to provide a simple S3 class to represent a
vector of binary objects, aka blobs. The blob class is a
lightweight wrapper around a list of raw vectors, suitable for inclusion
in a data frame.
In most cases you will not need to use this package explicitly: it will be used transparently by packages that need to load BLOB columns from databases or binary file formats.
# The easiest way to get blob is to install the whole tidyverse: install.packages("tidyverse") # Alternatively, install just blob: install.packages("blob") # Or the the development version from GitHub: # install.packages("devtools") devtools::install_github("tidyverse/blob")
To create a blob, use blob(), new_blob() or
as_blob():
library(blob) x1 <- charToRaw("Good morning") x2 <- as.raw(c(0x48, 0x65, 0x6c, 0x6c, 0x6f)) new_blob(list(x1, x2)) #> <blob[2]> #> [1] blob[12 B] blob[5 B] blob(x1, x2) #> <blob[2]> #> [1] blob[12 B] blob[5 B] as_blob(c("Good morning", "Good evening")) #> <blob[2]> #> [1] blob[12 B] blob[12 B]
