Re: [R] simple graphing question

2008-04-08 Thread benlafleche
This is maybe not the most elegant way, but it does de job. You first  
put f$RM values in negative form. Then you plot your graph without the  
x axis labels. After, you create the labels you want.

Try this :

f - (structure(list(TKN = c(0.103011025, 0.018633208, 0.104235702,
0.074537363, 0.138286096), RM = c(215, 198, 148, 119, 61)), .Names =  
c(TKN,
RM), class = data.frame, row.names = 25:29))

f$rms=f$RM*(-1)
plot(f$TKN~f$rms ,xaxt=n, type=b)

axis(side=1, seq(min(pretty(f$rms,n=3)),max(pretty(f$rms,n=3)),50),  
labels=seq(min(pretty(f$rm,n=3))*(-1),max(pretty(f$rm,n=3))*(-1),-50))

 Sorry, to have the x-axis to go from 200 to 0 or to reverse the x
 points-  the line starts on the left hand side of the graph at   
 x=215,
 y=0.10301103   ...   and end with x=61, y=0.13828610. does this make
 sense?  reverse order x-axis in excel is what I would use if this
 helps

 I would like to reverse the X-Axis.  How do I do this?

[R] as.character ()

2008-03-31 Thread benlafleche
Hello,

I'm trying to tranform a numeric vector into a character vector.

  x=c(2.00,1.20,5.00,6.56)
  y= as.character(x)
  y
[1] 21.2  56.56

What I want is :

[1] 2.001.20  5.006.56


Does someone know how to do this please ?
