[R] FW: Combined grouped and stacked bargraph

[Nicola Van Wilgen]

Dear R list,

It appears that my request from yesterday got a bit garbled. I have
tried to rephrase and retype it - please let me know if you can help me
- I am having some trouble drawing a bar-graph with two groups, both of
which are stacked.

I would like to plot the conservation status according to two
classifications (i.e. my groups - IUCN status and national status), and
for each of those groups I would like data for the marine and
terrestrial species to be stacked. My data look like this (where the
names for the columns are conservation status': NE, LC, NT, VU, EN and
CR; and the matrix name is cs.not.log.bp):

IUCN.Terrestrial        168  41  5  4  4  1

IUCN.Marine              69   6  4  2  2  0

National.CS.Terrestrial  16 148  7  7  4  2

National.CS.Marine       69   6  4  2  2  0

I have tried the following code, but it does not work:

barplot(cs.not.log.bp[c(1:2),], xlab = "Conservation status", ylab =
"Number of species", col = c("grey90","grey80"),names = cs.names, ylim =
c(0,250), space = 2)

barplot(cs.not.log.bp[c(3:4),], col = c("grey60","grey30"), beside =
T,add = T,names.arg = NA)

legend("topright",c("IUCN Terrestrial","IUCN Marine","National CS
Terrestrial","National CS Marine"),  col =
c("grey90","grey80","grey60","grey30"), pch = 15)

What happens is that some of the data in the second group stacks onto
the first group and then the remainder forms a second group. I would
like only "like" data (i.e. from the same database row) to stack within
a group.

There was one other similar post on the R-list
(http://r.789695.n4.nabble.com/barplot-question-td3670861.html ) where
the user had the same problem as I did, but it does not seem that this
was resolved.

Please let me know if you have any suggestions.

Thanks and best wishes,

Nicola

Dear R list,

 

I am having some trouble drawing a bar-graph with two groups, both of
which are stacked.

 

A sample of my data (IUCN and national conservation status for marine
and terrestrial species) look like this:

Status

IUCN Terrestrial

IUCN Marine

National CS Terrestrial

National CS Marine

NE

168

69

16

69

LC

41

6

148

6

NT

5

4

7

4

VU

4

2

7

2

EN

4

2

4

2

CR

1

0

2

0

 

I would like to plot the conservation status for two groups (IUCN status
and national status), and for each of those groups I would like data for
the marine and terrestrial species to be stacked. I needed to transpose
the data to plot correctly, so my data in the code below look like this
(where the names for data in the columns are NE, LC, NT, VU, EN and CR;
and the matrix name is cs.not.log.bp):

 

IUCN.Terrestrial        168  41  5  4  4  1

IUCN.Marine              69   6  4  2  2  0

National.CS.Terrestrial  16 148  7  7  4  2

National.CS.Marine       69   6  4  2  2  0

 

I have tried the following code, but it does not work:

 

barplot(cs.not.log.bp[c(1:2),], xlab = "Conservation status", ylab =
"Number of species", col = c("grey90","grey80"),

  names = cs.names, ylim = c(0,250), space = 2)

barplot(cs.not.log.bp[c(3:4),], col = c("grey60","grey30"), beside =
T,add = T,names.arg = NA)

legend("topright",c("IUCN Terrestrial","IUCN Marine","National CS
Terrestrial","National CS Marine"),

  col = c("grey90","grey80","grey60","grey30"), pch = 15)

 

What happens is that some of the data in the second group stacks onto
the first group and then the remainder forms a second group. I would
like only "like" data to stack within a group.

 

There was one other similar post on the R-list
(http://r.789695.n4.nabble.com/barplot-question-td3670861.html ) where
