juicr package for R

purpose of the juicr package

juicr is a GUI interface to automated, semi-automated, and manual tools for extracting data from scientific images -- like scatter or bar plots that contain data, or other images with information that can be converted numerically or coordinates classified. More information about juicr can be found at http://lajeunesse.myweb.usf.edu.

installation instructions and dependencies

juicr has an external dependency that needs to be installed and loaded prior to use in R. This is the EBImage R package (Pau et al. 2010) available only from the Bioconductor repository: https://www.bioconductor.org. To properly install juicr, start with the following R script that loads the Bioconductor resources needed to install the EBImage (also accept all dependencies):

install.packages("BiocManager"); 
BiocManager::install("EBImage")
library(metagear)

This dependency sometimes results in CRAN failing to generate a binary of juicr for your OS -- which sadly happens often. In this case install from the source, for example:

install.packages("juicr_0.1.tar.gz", repos = "http://cran.us.r-project.org", type = "source", dependencies = TRUE)
library(juicr)
