[R] adjust space between horizontal legend text in a barplot

[arun]

Hi,

Sorry about that.  My mistake.


Try this:
 barplot(VADeaths, names=rep("", 4), col=gray(1:3/4+0.01)) 

legend("bottom", legend=expression(scriptstyle("Strongly disagree/disagree"),scriptstyle("Neutral"),scriptstyle("Strongly agree/agree")), fill=gray(1:3/4+0.01), inset=-0.2, bty='n', horiz=T, x.intersp=0.5,xjust=0,yjust=0,text.width=c(1,0.25,1))

#You can change the text.width value to increase or decrease the spacings.

A.K.

Thanks for the reply. 
The one you provide is the vertical legend not for horizontal legend. 
x.intersp=  simply spreads out the space between symbols and legend text. 

using the existing data in R for example, 
barplot(VADeaths, names=rep("", 4), col=gray(1:3/4+0.01)) #five levels in this data, but just for example purpose
legend <- c("Strongly disagree/disagree", "Neutral", "Strongly agree/agree")
par(xpd = TRUE) 
legend("bottom", legend=legend, fill=gray(1:3/4+0.01), inset=-0.2, bty='n', horiz=T, x.intersp=0.5)
