Dear ALL: I am teaching statistical packages class this semester, in R programing I am trying to explain the use of save() and load() with an example using the iris data. It seems that the save() function works, BUT when I tried to load the data back to R, it seems that there is a problem(s), I could not figure out what went wrong.
Any help would be highly appreciated. I saved the iris data in my computer in the text format, "iris.with.head.txt ". Here are my R codes: > irisdata<-read.table("G:/iris.with.head.txt", header=T) > > head(irisdata) Sepal.Length Sepal.Width Petal.Length Petal.Width Species 1 5.1 3.5 1.4 0.2 setosa 2 4.9 3.0 1.4 0.2 setosa 3 4.7 3.2 1.3 0.2 setosa 4 4.6 3.1 1.5 0.2 setosa 5 5.0 3.6 1.4 0.2 setosa 6 5.4 3.9 1.7 0.4 setosa *##### saving the data as an .rda* save(irisdata,file="G:/irisdataTest.rda") *##### load the data back to R* load(file="G:/irisdataTest.rda") >head(irisdataTest) Error in head(irisdataTest) : object 'irisdataTest' not found > irisdataTest Error: object 'irisdataTest' not found with many thanks abou ______________________ *AbouEl-Makarim Aboueissa, PhD* *Professor, Mathematics and Statistics* *Graduate Coordinator* *Department of Mathematics and Statistics* *University of Southern Maine* [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
