...z : non-numeric argument to binary operator As you may see, I am getting an error. Can anyone tell me how I can convert z and ez to numeric vectors, so that I can compute days between the corresponding dates in these vectors? thank you soyoko ______________________________________ Ms. Soyoko Umeno Graduate Research Assitant for the Illinois-Missouri Biotechnology Alliance (IMBA) at http://www.imba.missouri.edu/ Ph.D. Student at the Department of Agricultural and Consumer Economics at the University of Illinois at Urbana-Champaign Office Phone: 217-333-3417 or 217-333-0364 Fax: 217-244-4817 M...

Hi everyone, I am having a problem reading my data file in R. It only reads part of it, and stops doing it in half way through the data. I looked at the observation where reading stops, but it is really not different from the observations read it. I expanded the matrix size, but it did not help. I am using a text format to read the data file. Could someone help me? Thank you Soyoko

Hi, I would like to know if anyone knows how to draw a plot with two Y-axises and one X-axis? When you have two sets of y values that do not have the same scale, but correspond to the same x value, I would like to plot them on one graph. Could you please help me? Thank you Soyoko

...pch=7 ) axis(4) Then, I want to label the second y axis "pay2". I tried "title(ylab="pay2")", but it put this lable on the first y-axis. Does anyone know how to move this to the second y-axis?

...ficient estimates. Then, I want to know the variance of b*c/a (2). How am I going to get it? In Stata, I can just use "bs" function by defining the regression model (1) and the statistic of the interest(2). Help!!!
