blockr.io

Upload and download multiple file formats such as Excel, csv, xpt, etc. to and from a blockr data pipeline.

Installation

You can install the development version of blockr.io from GitHub with:

# install.packages("devtools")
devtools::install_github("BristolMyersSquibb/blockr.io")

Example

Read a CSV file and write to Excel:

library(blockr.core)
library(blockr.io)

serve(
  new_board(
    blocks = blocks(
      a = new_read_block(source = "path"),  # Browse for files
      b = new_write_block(format = "excel", mode = "download")
    ),
    links = links(ab = new_link("a", "b"))
  )
)

The unified new_read_block() supports multiple sources (browse, upload, URL) and formats (CSV, Excel, Parquet, etc.) with smart format detection. The new_write_block() can output to various formats and supports both download and filesystem modes.
