Stacked Bar chart

[Thiago Silva Teles]

Dear All,

I need to do a stacked bar chart with these arguments:

 B_tot  B_turn  B_nest   scale

 0.98    0.96     0.02       Local

 0.94    0.90     0.04      Habitat

But I am not getting!!!

Can someone help me?

Thiago.

Hi Thiago,

You first need to reshape your data, and then plot it. I'm taking a
guess here at what you want, but for example:

# Your data frame
d <- structure(list(B_tot = c(0.98, 0.94), B_turn = c(0.96, 0.9),
B_nest = c(0.02, 0.04), scale = structure(c(2L, 1L), .Label = c("Habitat",
"Local"), class = "factor")), .Names = c("B_tot", "B_turn",
"B_nest", "scale"), class = "data.frame", row.names = c(NA, -2L))

# first reshape
library(tidyr)
d1 <- gather(d, B, value, -scale)

# and then plot
ggplot(d1, aes(scale, value, fill=B)) + geom_bar(stat='identity')

Probably, but it would be much easier if you had described what you wanted
to do more clearly (e.g. what is on the x-axis? What is being stacked?)
and supplied your data in an easily usable form (the output from dput).

Anyway, I have assumed you didn't want the total to be part of the bars
and have made a data.frame, d, which looks like this with dput(d)

structure(list(b = structure(c(2L, 2L, 1L, 1L), .Label = c("B_nest",
"B_turn"), class = "factor"), scale = structure(c(2L, 1L, 2L,
1L), .Label = c("Habitat", "Local"), class = "factor"), value = c(0.96,
0.9, 0.02, 0.04)), .Names = c("b", "scale", "value"), row.names = c(NA,
-4L), class = "data.frame")

If you copy and paste that after "d <-" (without the quotes) on the
command line then you will have d.

Then, assuming scale (Local and Habitat) should be on the x-axis:

ggplot(d)+geom_bar(aes(x=scale,y=value,fill=b),stat="identity")

If that isn't what you want, you'll probably be able to get it from that.
