[R] Dot plot of character and numeric matrix
Dear List, I have a set of data which looks like this (small set of sample) A A 0.431 A A 0.439 A A 0.507 A G 0.508 A A 0.514 I will like to use this data to plot a dot plot, with the X-axis being of type character, and my y axis of type numeric. When I try to use the dot chart function, I get the error message 'x' must be a numeric vector or matrix, which I can understand it to be a result of the fact that I have characters AA, AG etc as my x-values. Any idea how I can go about doing this? Thanks in advanced!

As an example: chars-c(A,A,B) numbers-as.numeric(as.factor(chars)) #make this numerical plot(numbers,c(0.4,0.5,0.6),xaxt=n) #xaxt=n says to not plot the x-axis axis(side=1,at=numbers,labels=chars) #make the axis with labels On 23.01.2013, at 10:16, Ng Wee Kiat Jeremy wrote: Dear List, I have a set of data which looks like this (small set of sample) A A 0.431 A A 0.439 A A 0.507 A G 0.508 A A 0.514 I will like to use this data to plot a dot plot, with the X-axis being of type character, and my y axis of type numeric.

I think you need to become more familiar with the factor data type. Reread the Introduction to R document that comes with R. --- Jeff NewmillerThe . . Go Live...
