uint8
Please note per the posting guide linked below: "For questions about functions in standard packages distributed with R (see the FAQ Add-on packages in R <https://cran.r-project.org/doc/FAQ/R-FAQ.html#Add-on-packages-in-R>), ask questions on R-help. If the question relates to a *contributed package* , e.g., one downloaded from CRAN, try contacting the package maintainer first. You can also use find("functionname") and packageDescription("packagename") to find this information. *Only* send such questions to R-help or R-devel if you get no reply or need further assistance. This applies to both requests for help and to bug reports. " It appears you have not done this -- if you have, please say so. Given that, while you might get lucky here, you should not be surprised if you don't. This looks like *exactly* the sort of query that a maintainer could help you with.

Dear R users, I am trying to join two 8 bit integers, as defined by the "coolbutuseless/uint8" package, without success:
library(uint8)
x1 = uint8(3)> x1[1] = as.uint8(1) x1[2] = as.uint8(2)> x2 = uint8(3)> x2[1] = as.uint8(2)> x1[1] 1 2 0>
x2[1] 2 0 0> xx = c(x1,x2)> xx[1] 01 02 00 02 00 00 In the real application the first array (x1) is extremely large (order 15-20 Gbytes) while the second is relatively small, so that I cannot afford, given my RAM, to define a third array, as
x3 = uint8(length(x1)+length(x2))
and then fill its components, but I need to join the two arrays. Is anyone aware of the right procedure in R or so kind to give suggestions ? (A possibility would be to switch to C/C++, but I would prefer not to). Many thanks, Luca --
