search for: x1986

Dear all, I have produced a barplot and wish to alter the axes a little. In place of the variable names appearing on the x-axis, I'd like to have the numbers 1986 to 1995.

Hi all, how can I divide two tables of the same dimension so that all names are preserved, ie do not become NA? I have "tab1" and "tab2", each having names in the first column. I want "tab3" with the same names and values "tab1/tab2". Thanks, Serguei

...got stuck with this. I would like to compare each elements of a vector A with any of the elements in Vector B. For some reasons it does not work. > StartDate = as.Date("01/10/2007", "%d/%m/%Y") > TimeSpan = seq(StartDate, by = 'days', length = length(myAverageCWVs$X1986)) > TickLabels = c("2007-10-01", "2007-11-01", "2007-12-01", "2008-01-01") > TimeSpan[1:40] == TickLabels Here I would expect TRUE for teh first entry and then TRUE for the entry related to "2007-11-01".

Any suggestions would be gratefully received. Many thanks, Steve
