Re: [R] Remove Even Number from A Vector

Re: [R] Remove Even Number from A Vector
Hello, I found this email when looking for some help with R Studio. It's actually my daughter who is looking for help. It sounds like she is working with the very basics of this software, and her task is to write the code which would result in the extraction of "odd" data from a dataset of restaurant sales. This is a shot in the dark...please ignore if my question makes little or no sense. I have no working knowledge of R software. Thanks.

[R] R installation Ubuntu 10.04 missing dependency
To upgrade to R.3.5.2 from 3.4.4 I have been following the instructions at https://www.r-bloggers.com/installation-of-r-3-5-on-ubuntu-18-04-lts-and-tips-for-spatial-packages/ . I seem to have the repository properly connected and verified. I am getting an error: --- john@jonh-T510:~$ sudo apt install r-base r-base-core r-recommended Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help resolve the situation: The following packages have unmet dependencies: r-base-core : Depends: libreadline6 (>= 6.0) but it is not installable Recommends: r-base-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages. - Earlier I was getting another error r-base-core : Depends: libpng12-0 but it is not installable but that was cured by installing libpng12-0 via the Ubuntu Software app. I cannot find what appears to be an installable version of libreadlines6. Ubuntu reports that the up-to-date version of libreadlines7. Should I consider this an R issue or an Ubuntu issue? In any case, has anyone encountered the problem and beaten it?
