Dear R-users,
again two question...
# Question 1
Adding two lines of text to a plot, I am using:
# -------------------------------
plot(k[,1], k[,2], pch=16,
ylim=range((min(k[,2])-0.2):(max(k[,2])+1)))
a <- paste("Cor.:" ,cor(k[,2],k[,1]))
b <- paste(nrow(k), "Countries")
text(90, max((k[,2])-0.51), a)
text(90, max((k[,2])-0.83), b)
# -------------------------------
But the distance between the first and second line depends on the
scale of the y-axis.
Is there a solution to put the lines in the upper right corner,
independent of the y-scale?
# Question 2
My data.frame looks like:> u
country gdp50 w5073
1.AUS AUS 77.15967 2.1708460
1.AUT AUT 74.06830 1.8691745
1.BEL BEL 77.87497 1.7547546
1.CAN CAN 87.07300 1.3649655
[...]
To add labels on points in a plot I call:
text(x=u[,2]+chw, y=u[,3], labels=levels(u[,1]), adj=0 )
How can I label only the datapoints for 'CAN' and 'AUS'?
Thanks for any help
Patrick

However, You need to be careful in this case. Your data happens to be sorted by country, which makes it in the same order as the levels of the factor country. Another way to do this might be to use different symbols and give a legend.

Hello Patrick you can use special chars inside your string. For a linefeed you need '\n' c <- paste(a,b,sep='\n') text(90, max((k[,2])-0.51), c) gruess joerg Patrick Hausmann wrote:> > Dear R-users, > > again two question... > > # Question 1 > Adding two lines of text to a plot, I am using: > > # ------------------------------- > plot(k[,1], k[,2], pch=16, > ylim=range((min(k[,2])-0.2):(max(k[,2])+1))) > > a <- paste("Cor.:" ,cor(k[,2],k[,1])) > b <- paste(nrow(k), "Countries") > > text(90, max((k[,2])-0.51), a) > text(90, max((k[,2])-0.83), b) > # ------------------------------- > But the distance between the first and second line depends on the > scale of the y-axis. > > Is there a solution to put the lines in the upper right corner, > independent of the y-scale? > > # Question 2 > My data.frame looks like: > > u > country gdp50 w5073 > 1.AUS AUS 77.15967 2.1708460 > 1.AUT AUT 74.06830 1.8691745 > 1.BEL BEL 77.87497 1.7547546 > 1.CAN CAN 87.07300 1.3649655 > [...] > > To add labels on points in a plot I call: > text(x=u[,2]+chw, y=u[,3], labels=levels(u[,1]), adj=0 ) > > How can I label only the datapoints for 'CAN' and 'AUS'? > > Thanks for any help > Patrick > ------------- > Patrick Hausmann > Friedrich-Wilhelm Str. 37 - D-28199 Bremen > Tel. +49 421 5980631 - Fax. +49 421 5980632 > -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- > r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html > Send "info", "help", or "[un]subscribe" > (in the "body", not the subject !)
