You get frequencies just by asking for them with freq: compare svyhist(~enroll, dstrat, main="Survey weighted",col="purple",freq=TRUE) svyhist(~enroll, dstrat, main="Survey weighted",col="purple") If you mean that you want the heights of the bars to sum to 1, the simplest way I know of is to rescale the weights to sum to 1 and use freq=TRUE -thomas > Any advice/help would be appreciated. > > Thanks, > > Pradip Muhuri > > > > > > ###### svyhist - Density Histogram > > options( survey.lonely.psu = "adjust" ) > svyhist (~age_p, > subset (nhis, xspd2=='SPD'), breaks=MyBreaks, > ylim = c(0,0.040), > main= " ", > col="red", > xlab="Age at Interview (SPD Category)" > ) > lines (svysmooth(~age_p, bandwidth=5,subset(nhis, xspd2=='SPD')), lwd=2) > > > ________________________________________ > From: Anthony Damico [ajdam...@gmail.com] > Sent: Monday, October 01, 2012 10:07 AM > To: Muhuri, Pradip (SAMHSA/CBHSQ) > Cc: R help > Subject: Re: [R] svyboxplot - library (survey) > > 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 > > > > > > > > On Mon, Oct 1, 2012 at 9:50 AM, Muhuri, Pradip (SAMHSA/CBHSQ) > <pradip.muh...@samhsa.hhs.gov<mailto:pradip.muh...@samhsa.hhs.gov>> wrote: > 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 > > ################################################### > nhis <- svydesign (id=~psu, strat=~stratum, weights=~wt8, > data=tor, nest=TRUE) > > svyboxplot (dthage~xspd2, subset (nhis, mortstat==1), col="gray80", > varwidth=TRUE, ylab="Age at Death", xlab="SPD Status: 1-SPD, > 2=No SPD") > > > Pradip K.
