[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) S
