[R] read.csv and Decimal places

Hi, Novice UsR here. I have a csv file that contains 13 columns of numeric data that have decimal places (for the most part). After reading in the file RevFCast = read.csv("RevAnalysisNov2016_April2018.csv", header=TRUE, dec = ".", stringsAsFactors=FALSE) and viewing the data View(RevFCast)

[R] Comparing figures?

Hello, I am working on tests to compare figures. I have been using ImageMagick, which creates a figure signature, and I can compare a "test" figure signature against a saved "reference" figure signature. It seems to work pretty well. However, it is slow as it requires reading from the file
