...hed and examined 30 or so hits on Dr. Baron's search site, looked through my MASS book, my Data Analysis and Graphics Using R book, R news articles, and I have in my hand the lattice package instructions and have read and re-read the "scales" section. Here is the problem I am having. Scanf is a factor with 20 levels and the mean values for these levels are being plotted with CIs. I am trying to reduce the text size for the labels for this variable. The first function below does not attempt to set the text size for the y axes, and all works well. xx2 <- with(xx,summarize(q27a,...

It has long been known that the C specification of *scanf() leaves behavior undefined for things like int i; sscanf("9999999999999999", "%i", &i); C11 7.21.6.2 P12 "Matches an optionally signed integer, whose format is the same as expected for the subject sequence of the strtol function with the value 0 for the base argume...

...t thing > (i.e., report a failure) than the current behavior does. And with luck perhaps > we could eventually get POSIX to standardize this behavior. I'm not really a fan of stopping on an initial prefix. While UB allows anything, that's contrary to the abstract behavior defined for scanf (matching fields syntactically then value conversion) and does not admit easily sharing a backend with strto*. It's also even *more likely* to break programs that don't expect the behavior than just storing a wrapped or clamped value, since all the remaining fields will misalign with the co...

I'm having difficulty trying to figure out how to write an R wrapper for a C function that has a "scanf-like" argument list. Recall that in C, functions like scanf() return their values through a variable number of arguments whose type and number is determined by a format string. In C this is handled by parsing the format string and then applying the types and functions declared in <stdar...

The context to this is that nbdkit uses sscanf to parse simple file formats in various places, eg: https://github.com/libguestfs/nbdkit/blob/b23f4f53cf71326f1dba481f64f7f182c20fa3dc/plugins/data/format.c#L171-L172 https://github.com/libguestfs/nbdkit/blob/b23f4f53cf71326f1dba481f64f7f182c20fa3dc/filters/ddrescue/ddrescue.c#L98 We can only do...

I am trying to use dtrace to trace all sscanf calls. I am able to use pid provider for this. But my application forks off children at times to handle requests. Is there a way I can stop the child process immediately after it is started so that I can attach a pid provider to that and trace the scanf calls in it? I have tried usi...
