Subject: [R] plotting multiple variables in 1 bar graph
I'd greatly appreciate your help in making a bar graph with multiple
variables plotted on it. All the help sites I've seen so far only plot
1 variable on the y-axis
Data set:
I have 6 sites, each measured 5 times over the past year. During each
sampling time, I counted the occurrences of different benthic
components (coral, dead coral, sand, etc.) over 5 transects in each
site
site time transect coral deadcoral sand rubble
.....
S1 time1 trans1 10 15 10
4
S1 time1 trans2 5 4 10
6
S1 time1 trans3 10 2 5
7
.
.
.
S5 time5 trans5 6 3 1
6
I used aggregate to get the means of the individual variables (coral,
dead coral, etc.) using the site and time as grouping factors.
aggregate.plot(deadcoral, by=list(SITE=site, TIME=time), FUN=c("mean"),
error=c("sd"), legend.site="topright", bar.col=rainbow(6))
Where is aggregate.plot from?
What I need now is to plot all the variables in 1 site as they change over time.
Something like
barplot(VADeaths, beside = TRUE,
col = c("lightblue", "mistyrose", "lightcyan",
"lavender", "cornsilk"),
legend = rownames(VADeaths), ylim = c(0, 100))
title(main = "Death Rates in Virginia", font.main = 4)
or maybe you could try ggplot2

What Excel produced: <http://r.789695.n4.nabble.com/file/n4647099/abdeens_benthic_cover.jpg> (The image has mean %cover as the y-value instead of mean count but the example still applies) I've spent several hours looking for code to do this but didn't find anything. I'd use the Excel graph except that it doesn't have the sd or se bars. -- View this message in context: http://r.789695.n4.nabble.com/plotting- multiple-variables-in-1-bar-graph-tp4647099.html Sent from the R help mailing list archive at Nabble.com.
