splitting a data.frame
I have the following (simple!?) problem which I am unable to find a
relatively trivial solution to.
If I have a dataframe,
A 1
A 7
B 4
B 5
C 3
D 3
D 2
E 5
F 5
F 6
I would like to create a new data.frame in the form
ID pt1 pt2
A 1 7
B 4 5
C 3 NA
D 3 2
E 5 NA
F 5 6
so that for each identifier, in this example, A...F I have a column for
each observation for each identifier... (with a maximum of 2 obs per
identifier, if only 1 obs exist then the second obs pt2 is set to NA)

Nested SEXP functions
...s, we'll call this:
SEXP XtimesY(SEXP X,SEXP Y); // X*Y
SEXP XminusY(SEXP X,SEXP Y); // X-Y
SEXP tX(SEXP X); // X^T
SEXP mycholinv(SEXP V); // Use cholesky decomposition for inverse
Now, what I'm noticing is that if I call each routine individually
such as:
pt1=XtimesY(X,beta); // X*beta
pt2=Xminus(Y,pt1); // Y-X*beta
pt3=tX(pt2); // (Y-X*beta)^T
pt4=mycholinv(V); //V^{-1}
pt5=XtimesY(pt2,pt4); // (Y-X*beta)^T V^{-1}
result=XtimesY(pt5,pt2); //(y-X*beta)^T V^{-1} (y-X*beta)
Then the result is correct. But if instead I want to save some lines
of code, and I use:

[LLVMdev] PROPOSAL: struct-access-path aware TBAA
...they *must* point to the same memory.
For this specific case, I actually tried both g++ and gcc last night,
there is no difference.
I'm wondering why the "dynamic type" would help to make TBAA 100% safe
and also helpful.
Suppose point-to set for the two mem-access are pt1 and pt2,
dyn-type1 = union-of-all-type-of-the-element-in-pt1,
dyn-type2 = union-of-all-type-of-all-element-in-ptr2.
If dyn-type1 and dyn-type2 are disjointed, then pt1 and pt2 must be
disjoint, which means the point-to
analysis already prove these two memory access are not alias. We don't
need TBAA...

Another loop avoidance question.
...## Basic paramters
k1=3
k2=2
n=10
m1 = matrix (1:(n*k1), nrow=n, ncol=k1)
m2 = matrix (1:(n*k2), nrow=n, ncol=k2)
## Approach 1: loop on k1
output1 = matrix(0,nrow=n,ncol=k2)
pt1 = proc.time(for (i in 1:k1) output1 = output1 + m1[,i]*m2)
## Approach 2: loop on k2
output2 = matrix(0,nrow=n,ncol=k2)
pt2 = proc.time(for (i in 1:k2) output2[,i] = rowSums( m1*m2[,i] ))
## Same result
sum(output1-output2)

[LLVMdev] PROPOSAL: struct-access-path aware TBAA
....
If I fabricate a caller by stealing some code from your previous
example, see bellow.
I think these code & your previous example (about placement new) share
the same std. I'm wondering
if gcc can give a correct result.
foo_caller() {
T1 t1;
T1 *pt1;
T2 *pt2 = new (pt1) T2;
foo(pt1, pt2);

I personally believe that in the context of type-based AA, correctness
is a subjective term:-).
If the user smell something fishy, it is up to user to disable such opt,
there is no other
way around. TBAA is just to find the a sweet spot between precision &
safeness.
Unfortunately, in the context of TBAA, precision & safeness usually come
at each other's expense...

I want to plot data that contains dates on the x axis. Then I want to fit a line to the data. I have been unable to do it.
