Hi,
I need to convert general numbers to percentages in R to create a
boxplot for purposes of comparison.
Can you please tell me how I can do that? My data is attached as a
csv file.
No, it's not. Please read the Posting Guide. (.csv is not an accepted
file extension)
Are you sure you want a box-and-whiskers plot? I would think that an
exression such as a percentage wouldn't make much sense when plotting
values that depend on a distribution of raw numbers. Maybe you meant
barplot? Nonetheless, let's press on...
print, format, or sprintf can create strings from numbers. Generally
one would multiply a proportion by 100 and stick a "%" sign after it.
And usually the labels can be in a form:
bwp1 <- boxplot(count~spray, data = InsectSprays, axes=FALSE,col =
"lightgray");
axis(2 , at=InsectSprays$count, labels= sprintf("%.1f%%",
100*InsectSprays$count/sum(InsectSprays$count)) )
# not sure that made any sense.
axis(1 , at=1:6, labels= bwp1$names )
.
Thanks.
Daniel
