Dear Anthony,

Yes, I can follow the example code you have given.  But, do you know from the 
code shown below (following Thomas Lumley's "Complex Surveys") why I am getting 
the boxplot of dthage for just xspd=1, not xspd2=2?

My intent is the make this code work so that I can generate similar plots on 
other continuous variable.

Any help will be appreciated.

Thanks,

Pradip

             varwidth=TRUE, ylab="Age at Death", xlab="SPD Status: 1-SPD, 2=No 
SPD")

using a slight modification of the example shown in ?svyboxplot


# load survey library
library(survey)

# load example data
data(api)

# create an example svydesign
dstrat <- svydesign(id = ~1, strata = ~stype, weights = ~pw, data = apistrat,
    fpc = ~fpc)

# set the plot window to display 1 plot x 2 plots
par(mfrow=c(1,2))

# generate two example boxplots
svyboxplot(enroll~stype,dstrat,all.outliers=TRUE)
svyboxplot(enroll~1,dstrat)

# done



# alternative: not as nice

# set the plot window to display 2 plots x 1 plot
par(mfrow=c(2,1))

# generate two example boxplots
svyboxplot(enroll~stype,dstrat,all.outliers=TRUE)
svyboxplot(enroll~1,dstrat)

# done

Hello,

I have used the library (survey) package for boxplots using the following code.

Could anyone please tell me why I am getting only 1  boxplot instead of 2 
boxplots (1-SPD,  2-No SPD).

What changes in the following code would be required to get 2 boxplots in the 
same plot frame?

Thanks,

Pradip
