[R] Lattice plots and missing x-axis labels on second page

2011-11-02 Thread Evans, David G (DFG)
Hello, 
I'm trying to make a lattice plot (using xyplot()). I have included a
layout=c(3,4) statement, giving me 12 plots per page and an
as.table=TRUE statement, directing the way the plots are laid out.  I
have 18 plots altogether and so 6 of them end up on the second page.
Everything looks fine for the first page, but the x-axis labels (e.g.
1993, 1994...) are all missing on the second page.  The x-axis variable
name (Year) is there at the bottom, however.   Any help is
appreciated. Thanks.

I should say I'm using Windows-7, R version 2.13.0 and lattice version
0.19-33.  I've pared down my code to this :

pdat = read.table(RGRAPHSDGE.csv,header=T,sep=,,fill=T)
print(xyplot(pdat$NITRATE~pdat$DATEYR|pdat$WELL,
as.table=TRUE,
layout=c(3,4),
xlab=Year,
ylab=Nitrate mg / litre,
strip=FALSE
)) 

First 3 lines of pdat looks like this:
  WELL   DATEYR NITRATE
1 ALASKA CHILDRENS SERVICES 1993.8360.81
2 ALASKA CHILDRENS SERVICES 1994.8500.91
3 ALASKA CHILDRENS SERVICES 1995.8030.94

Thanks again.

[R] lattice histogram and grouping

2011-03-21 Thread Evans, David G (DFG)
Hi,
From the following pseudo-code (tweaked from another user): 
library(lattice)
variable-sample(rep(1:2,100))
individual-rep(1:3, length(variable))
group-rep(LETTERS[1:2],length(variable)/2)
mydata-data.frame(variable,individual,group)
individual-as.factor(individual)
group-as.factor(group)
histogram(~variable|individual+group)

I get six panels, one for each of  individuals 1-3 in group A and one
for each of individuals 1-3 in group B .  
What I want is three panels, one for each individual, but with  A and B
paired in the same panel.  I think the groups=argument does this sort
of superposition for other lattice functions, but is apparently
unavailable for histogram().  

Thanks very much for any help.

[R] lattice histogram function and groups

2011-03-18 Thread Evans, David G (DFG)
Hi,

From the following code (tweaked from another user): 

 

variable-sample(rep(1:2,100))

individual-rep(1:3, length(variable))

group-rep(LETTERS[1:2],length(variable)/2)

mydata-data.frame(variable,individual,group)

individual-as.factor(individual)

group-as.factor(group)

histogram(~variable|individual+group)

 

I get six panels, one for each of  individuals 1-3 in group A and one
for each of individuals 1-3 in group B .  

What I want is three panels , one for each individual, but with  A and B
paired in the same panel.  I think the groups=argument does this sort
of superposition for other lattice functions.  

 

Thanks very much for any help.
