**NEW TO R**-been trying to teach myself with no prior experience in computer languages, so I apologize if I am poor at using technical terms Hi, I have perused some of the previous posts on this topic and tried their solutions, but am still coming up with error messages(sometimes more than 50 at a time)
I have: a csv file with four columns(that I have read into R, no problem, we will call it DATA) date, Location1, Location2, total Dates cover almost a year location values are number of fish seen at that location I would like to show a stacked bar plot so someone can see the breakdown for total fish seen on any particular day. I was able to create a simple bar plot for total number of fish versus Date, but when I have tried to make a stacked graph it creates four bars(one for each column). Do I have to convert my data so each date has its own column or is there a way I can use my data as is? script I have tried: barplot(as.matrix(DATA)) barplot(t(DATA),names.arg=DATA$Date) fish<-table(DATA$Location1,DATA$Location2) barplot(fish,names.arg=DATA$Date) Any help is appreciated. -- View this message in context: http://r.789695.n4.nabble.com/using-csv-file-for-stacked-bar-plot-rows-to-columns-tp3899909p3899909.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list 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.
