that would save you lots of time as you wouldn't have to reinvent the

Hi, there,
I cannot get accurate value for calculation.
for example:
ld-sqrt(1*0.05*0.95*0.05*0.95)
0.05*0.95-ld=-6.938894e-18
0.05*0.95-ld==0 is False.
I met this problem in my program, how can I handle it. Thanks.
I think what you are

The gp.plot function has a type option that can either be 'p' for points
or 'l' for lines, the function is not that complicated, you could easily
add additional options.
I don't know why your code is not creating the pdf file, you could try
plotting to the screen first (don't change the output
Thanks for all response. Here is more closer to my question,
p-0.05
f-0.05
ld-sqrt(f* (1 - f) * p * (1 - p))
D - (p * (1 - f) - ld)/p
d - ((1 - p) * f - ld)/(1 - p)

There was some discussion a while back of an R pgf driver
for latex. Is anyone working on that?

How can I solve this problem?

Hi All,
I am a new user in R and I would like to buy a book that teaches me how to

Does anyone recommend some books or websites where I can learn R.
Thanks
