[External] Re: ctrl -c while executing --progress --size-only --partial results in unhidden but incomplete file
Rsync has no memory of what other instances of rsync have done in the past. An existing file with a different name is of no interest to it unless --delete in which case it would be deleted. Maybe what you really want is --partial-dir?

skipping rows in trellis key
Hi, I would like to add a key to my trellis plot using draw.key. Here is what I want: 3 x 6 key where the first row is a header. row 1: empty, "S-R Mapping", "R^2" row 2: pch=17, "Color", 0.951 row 2: pch=17, "Shape", 0.934 ect... The problem is that I would like the cell in the upper left corner to be empty (a placeholder) with the remaining

[R] documenting s4 methods in package

[LLVMdev] struct with signed bitfield (PR17827)
I've been diagnosing this bug: http://llvm.org/bugs/show_bug.cgi?id=17827 Summary: I think the following program miscompiles at -O1 because the fact that 'f0' is a signed 3-bit value is lost in the unoptimized LLVM IR. How do we fix this? $ cat bitfield.c /* %struct.S = type { i8, [3 x i8] } ??? */ struct S { int f0:3; } a; int foo (int p) { struct S c = a; c.f0 = p & 6;

object size vs. file size
Hi, There is rather large discrepancy in the size of the object as it lives in R and the size of the object when it is written to the disk. The object in question is an S4 of a homemade class "sa". I first call a function that writes a list of these objects to a file called "data.RData". The size of this file is 14,411 KB. I would assume on average then, that each list

I suspect my later interpretation is false because the estimated values do not change after each and every replication of the analysis. But I thought I might ask.

This is particularly interesting when the original divisor is a constant so you can materialize the reciprocal at compile-time. You’re right that in either case, this optimization should only kick in when
