Dear R-help members, I'm processing a large amount of MODIS data where quality assessment information is stored as an integer value for each pixel. I have to converted this number to an 8 digit binary flag to get access to the stored quality code (e.g. in2bin(165,8) = 1 0 1 0 0 1 0 1). Unfortunately, I did not manage to find a package providing a fast function to do so. I need to run

Full_Name: Clemens Bockmeyer Version: 2.9.0 OS: Submission from: (NULL) (193.174.111.250) Dear helpdesk, the following bug occurs when working with BRB Array tools trying to generate a heat map: Error in rgb (bitAnd(Max color 255), bit and Max color %/%256, 255 bit And Max color... could not find function "bitAnd". Error occured while executing the following R command: myplot.image.array (TRUE). Error may be memory related or due to size of graphic file. Try again with fewer genes or... My quest...

I cannot find any R function or operator that performs a binary AND operation, as performed by Fortran built-in function "iand". Ideally either R operator "&" or "&&" should do that. But some tests proved they do not: > A<- 1 > B <- 2 > A [1] 1 > B [1] 2 > as.numeric(A&B) [1] 1 > as.numeric(A&&B) [1] 1 The binary

I am acquiring some sampled data that is time-stamped (with a POSIXct). Some of the data is in the form of "counters" -- that is, what is interesting isn't value of a given counter at a given time, but the change in the counter from one sample to a later one. As the counters are only incremented, they would be perceived to be monotonically increasing -- ideally. Unfortunately, the

Several years ago, I hacked together functions using the .C call for bit operations: bitAnd, bitOr, bitFlip, bitShiftL, bitShiftR, bitXor and crc(char). Are there any more standard alternatives for these? If not, and, if any there is any interest, I would be happy to help package what I have for distribution. Additionally, I would interested in hearing offline from anyone using R/S...
