Readers, Previous questions about this requirement have been for m$ users, my failure occurs using linux. I have tried to add the delta (?) symbol to the y axis label and the result is &D, using the command: ...ylab="?t"... Any advice please? rhelp at conference.jabber.org mandriva 2008 r 251 (27-06-07)

Readers, For this data set: testvalues<-c(10,20,30,40) How to amend the plot instruction: plot(testvalues,ann=FALSE,type='l',yaxt='n',xaxt='n') so that x axis ticks labels can be added to existing graph with arbitrary value such as 0,100,200,300)? Thanks in advance. -- r2151

Readers, I am having difficulty understanding how to enter commands into r. I have data arranged as: 100, 200, 300 5.6, 6.7, 7.8 8.9, 9.0, 0.1 1.2, 2.3, 3.4 The data is saved in csv format and I use the command 'read.table' to import into r.
