major data extraction problem. help needed please

hello! I am having issues extracting a data set into Rstudio. I would really appreciate any help/insight anyone might be able to provide, thank you!

I am unsure of what is meant by vector of 2.0mb and why it cant be allocated.
Thank you for your time

That error message means the memory is not available to store the object ukb. But 2.1Mb is tiny, as such things go. The first thing I would do is check the memory usage on the computer. Then shutdown RStudio and check the memory usage on the computer. Then restart RStudio and check the memory usage again. Finally, assuming the previous steps show plenty of memory available, I would try to read in the file again.

Thank you so much. I will try that now
