[R] plotting a point graph with data in X-axis
Dear all, I have two data frame, on with a complete list of my field survey with frequency data of a sample species. This data frame looks like: simulation-data.frame(cbind(my.year=c(rep(2000,8),rep(2001,12),rep(2002,12)),my.month=c(5:12,1:12,1:12))) simulation$year.month-paste(simulation$my.year,_,ifelse(simulation$my.month=10,simulation$my.month,paste(0,simulation$my.month,sep=)),sep=) simulation$freq-sample(1:40,32) attach(simulation) plot(year.month, freq) As you can see, I have a collumn with the year and month of my samples, and a freq variable with simulated data. I would like to plot this data but when I try to use the plot showed above, I get a error message. After bypass this problem, I would like add points in my graph with simulated data for only a random number of survey month, but I need that the full range of surveys be kept on the X-axis. Just to simulate a sample I am using: simulation.sample-simulation[sample(1:length(year.month),8, replace=F),] simulation.sample$freq-sample(1:40,8) Any ideas?

Re: [R] plotting a point graph with data in X-axis
You have to have a valid 'date' object on the x-axis. Try this: simulation-data.frame(cbind(my.year=c(rep(2000,8),rep(2001,12),rep(2002,12)),my.month=c(5:12,1:12,1:12))) simulation$year.month-paste(simulation$my.year,_,ifelse(simulation$my.month=10,simulation$my.month,paste(0,simulation$my.month,sep=)),sep=) simulation$freq-sample(1:40,32) # create POSIXct time simulation$time - ISOdate(simulation$my.year, simulation$my.month,1) attach(simulation) plot(time, freq) On 5/8/07, Milton Cezar Ribeiro [EMAIL PROTECTED] wrote: Dear all, I have two data frame, on with a complete list of my field survey with frequency data of a sample species.

- use proper spacing to make it easier to read - start off with set.seed to make it reproducible - omit cbind and combine all the rep's into one rep in first line - make the date column a known date class (here Date), set.seed(1) sim - data.frame( my.year = rep(2000:2002, c(8, 12, 12)), my.month = c(5:12, 1:12, 1:12), freq = sample(1:40, 32) ) sim$date - as.Date(paste(sim$my.year, sim$my.month, 1, sep = -)) plot(freq ~ date, sim) On 5/8/07, Milton Cezar Ribeiro [EMAIL PROTECTED] wrote: Dear all, I have two data frame, on with a complete list of my field survey with frequency data of a sample species.

Re: [R] plotting a point graph with data in X-axis
R understands only numerical and Date class values for axis. So either a) plot them using the sequence 1, ..., 32 and then explicitly label them. Here is an example: n - length(year.month) plot( 1:n, freq, xaxt=n) mtext( text=year.month, side=1, at=1:n, las=2 ) b) or create the dates in Date format. This option is preferable if the dates were varying unequally. x - seq( as.Date(2000-05-01), as.Date(2002-12-01), by=1 month ) plot(x, simulation$freq) BTW, you could also have created year.month via paste( rep( 2000:2002, c(8,12,12) ), formatC( c(5:12,1:12,1:12), width=2, flag=0 ) , sep=_ ) Regards, Adai Milton Cezar Ribeiro wrote: Dear all, I have two data frame, on with a complete list of my field survey with frequency data of a sample species.

Re: [R] plotting a point graph with data in X-axis
One other idea. If your dates are continguous, as they are here, you might want to use a ts series for this. Using the same sim as in my prior post: set.seed(1) x - with(sim, ts(freq, start = c(my.year[1], my.month[1]), freq = 12)) x Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 2000 11 15 22 34 8 32 33 38 2001 21 2 7 6 20 40 35 13 18 23 9 17 2002 19 5 12 3 28 29 1 16 27 4 25 39 plot(x) On 5/8/07, Gabor Grothendieck [EMAIL PROTECTED] wrote: - use proper spacing to make it easier to read - start off with set.seed to make it reproducible - omit cbind and combine all the rep's into one rep in first line - make the date column a known date class (here Date), set.seed(1) sim - data.frame( my.year = rep(2000:2002, c(8, 12, 12)), my.month = c(5:12, 1:12, 1:12), freq = sample(1:40, 32) ) sim$date - as.Date(paste(sim$my.year, sim$my.month, 1, sep = -)) plot(freq ~ date, sim) On 5/8/07, Milton Cezar Ribeiro [EMAIL PROTECTED] wrote: Dear all, I have two data frame, on with a complete list of my field survey with frequency data of a sample species.
