A Worked Out Example of Managing with abbyyR"

In abbyyR: Access to Abbyy Optical Character Recognition (OCR) API

Load the package

To install the package from CRAN, type:

install.packages("abbyyR")

To get the latest development version from GitHub:

# install.packages('devtools')
devtools::install_github('soodoku/abbyyR')

Next, load the package.

library(abbyyR)

Set credentials

Your first task on loading the package should be to set the credentials - application ID and password. If you haven't already, you can get this information http://ocrsdk.com/. Once you have the application ID and password, set it via the setapp function.

setapp(c("factbook", "7YVBc8E6xMricoTwp0mF0aH"))

listTasks(fromDate="2015-05-30T20:28:43Z", toDate="2015-05-31T20:28:43Z")

## No tasks in the application.

List Finished Tasks

listFinishedTasks()

Deleting an already deleted task will result in an error.

#deleteTask(taskId="47f9b0d4-79a2-4aed-b656-2683a85ac203")
