similar to: histogram of frequencies (PR#861)

Full_Name: Stephan Schlueter Version: 1.9.0 OS: Submission from: (NULL) (217.184.109.24) During my studies, I found a fault in the hist()-function: If you have a vector x with values around zero and also bigger than 10,000,000 , there will be a shift of -max(x)/10,000,000 in the hist-datas. See my example: x<-runif(10000) hist(x,breaks=c(seq(-3,3,0.1)),prob=TRUE) #everything ok, but

I was using the hist() function to create a frequency table of some network traffic data. The range in values is rather large, from 0 till just under 10e12. Calling hist(x, breaks=c(0,1000,1e6,1e9,1e12),plot=F,freq=T) causes hist() to return : $breaks [1] -1.0000e+05 1.0100e+05 1.1000e+06 1.0001e+09 1.0000e+12 Is this recalculation of the breaks by hist() intended?

Hi, if I dermine the break points using the hist() function and then try to re-use these in a new histogram, R fails. Here is an example of the problem: ##First, plot a histogram: data(islands) foo <- hist(islands,freq=T) ##Now, try plot it again, with the previously determined break points: hist(islands,breaks=foo$breaks,freq=T) ##... this lead to the warning message: Warning message:

Hi, We have several llvm fuzz targets running on OSS-Fuzz, a continuous automated fuzzing service: https://github.com/google/oss-fuzz https://www.usenix.org/sites/default/files/conference/protected-files/usenixsecurity17_slides_serebryany.pdf It has reported a few bugs in cxa_demangler, clang, and dwarfdump already, and we expect to add more fuzz targets to it soon (llvm-isel-fuzzer,

Hi Mitch, Thank you for the response. 1. You don't need to build the library with `-fsanitize-coverage=...`, using `-fsanitize=fuzzer-no-link,address` should be sufficient. - Acknowledged 2. (although you can actually build object files/shared libraries with -fsanitize=fuzzer, and the libFuzzer main won't be linked, if this makes your build process easier). - with just the *fuzzer

I have a generic function test.equal <- function(obj1, obj2, ...) UseMethod("test.equal") however, the only argument that specific methods use is "fuzz" so I would like to change this to test.equal <- function(obj1, obj2, fuzz=???) UseMethod("test.equal") The problem is that some methods use slightly different default values for fuzz than others. How should

I am working of using libfuzzer and asan to test out a third-party library. As demonstrated in the tutorial, I wrote a fuzz target to fuzz a specific function in the library. The fuzz target is then linked to the library and compiles clean and I do see some tests generated by the fuzzer. However, I have some questions regarding the "right" way to go about doing this. I have doubts that

Hi all, I'm working on fuzzing Opus with OSS-Fuzz and have started with the decoder. Attached is a patch to add the corresponding fuzz target. Please let me know if there are any concerns?

Hi all, The blog entry [1] suggest that one of the buildbots constantly fuzzes clang and clang-format. However, the actual bot [2] only tests the fuzzer itself over a well-known set of bugs in standard software (eg. Heartbleed [3] seems to be among them). Has there actually ever been a buildbot that fuzzes clang/LLVM itself? Another (obvious?) fuzzing candidate would be the LLVM's bitcode

Thanks for your comments, Ralph and Jean-Marc. Please find attached the amended patch: - decodes a sequence of input packets rather than just one (I'm planning on using the Opus test vectors as the seed corpus) - decides on decoder setup and FEC independently of the packet data - uses Opus functions to parse ToC Cheers, Felicia On Sun, Jan 29, 2017 at 9:48 PM Jean-Marc Valin <jmvalin at

Hello, To indicate probability densities instead of counts on a histogram, I specify freq = FALSE. However, I expect that summing all top y coordinates over all the intervals of the histogram will provide 1. 1) v <- c(0.2885, 0.2988, 0.3139, 0.2615, 0.3179, 0.3163, 0.2583, 0.3052, 0.2527, 0.3147, 0.3235, 0.2408, 0.2480, 0.3108, 0.3577, 0.2829, 0.2694, 0.3275, 0.3314, 0.2639, 0.3076,

Hi, Recently I want to fuzz samba systematically (instead of functional fuzzing like OSS-Fuzz/samba). However, the fuzzer acts like smbclient and needs to establish a connection with the samba server via NTLM authentication. The NTLMSSP_Challenge sent by the server is not deterministic, which can render the fuzzing based on previously captured traffic futile. Does samba provide a fuzzing mode
