[R-SIG-Finance] zoo plotting - invalid 'ylim' value

[spencerg]

Hi, Gabor: 


      I just lost perhaps a day's work due to that very problem:  I 
couldn't get read.zoo to work, so I used read.table, which created 
factors, because some of my numeric columns included, ", NA", which got 
translated as a level " NA" (note this three character code with a space 
before the NA).  Then I did "as.matrix" of the data.frame that I thought 
was numeric;  the result was a zoo object with coredata of class 
character rather than numeric. 


      Best Wishes,
      Spencer
