[R] svyboxplot - library (survey)

[Muhuri, Pradip (SAMHSA/CBHSQ)]

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

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