plotting planes and lines in wireframe()
...e relation.... Hmm... Somewhat related, I would also like to plot a line in 3 d space... Finally, if you are feeling really brave, I am interested in doing all of this based on sums generating vectors (I know there is a linear algebra term for this) -- ie generate the plane based on c_1*v_1 + c_2*v_2 for c_1 and c_2 in reals. Thanks again to all you helpful folks! W

How to generate a correlation matrix with restrictions on its eigenvalues
Dear All, I would like to generate m positive real numbers c_i, I=1,...,m, such that (1) c_1 + c_2 + ... + c_m=m, (1) after being ordered into c_1 >= c_2 >= .... >=c_m>0, we have that c_m is of the same order of m^(-1/8), when m is sufficiently large. Thanks, -Chee [[alternative HTML version deleted]]

undef * 0
...that all bits of the ‘|undef|‘ could be 0, and optimize the ‘|and|‘ to 0. Likewise, it is safe to assume that all the bits of the ‘|undef|‘ operand to the ‘|or|‘ could be set, allowing the ‘|or|‘ to be folded to -1." As a result, LHS = (undef & undef) | (undef & undef) = c_1 | c_2 where c_1 and c_2 are constants and as a result, And finally, LHS = c where c is a constant; not undef. Please correct me if I am missing something. Best Regards, soham On 9/13/2016 7:27 PM, Sanjoy Das wrote: > Hi Soham, > > Soham Chakraborty wrote: > > As a result, the t...

sending a vector of characters as arguments for a function
Dear all, It seems to be a recurrent problem to me and I am asking your help to get over it once for all ... My idea is : I have variables C_1, C_2, C_3 ... that corresponds to vectors of size n, and I would like to cbind them. I get a vector of their names using : temp<- ls(pat="C") And I like to find a way to use this vector temp as an argument to cbind. Unfortunately, my various trials failed, here are some samples of...

undef * 0
Thanks for your answers. Another example of unsound transformation on Boolean algebra. According to the LLVM documentation (http://llvm.org/docs/LangRef.html#undefined-values) it is unsafe to consider ' a & undef = undef ' and ' a | undef = undef ' but 'undef xor undef = undef' is safe. Now, given an expression ((a & (~b)) | ((~a) & b)) where a and b are
