timespace.R - crash on line 77

[jaromf]

When running line 77 summary(ARdj <- glm(dja[2:n] ~ d of timespace.R, R Studio crashes and reports a "Segmentation fault" in the Bash terminal. I read on StackOverflow that this could be due to limited memory. I'm running Crostini / Debian on a Pixelbook with 8 GB ram and approx. 80 GB free disk space. Can anyone suggest a possible solution or troubleshooting tips?

Here's the result of running 'gc(ARdj)`

gc(ARdj)
Garbage collection 15 = 12+0+3 (level 2) ...
26.9 Mbytes of cons cells used (53%)
7.6 Mbytes of vectors used (12%)
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 502063 26.9 944981 50.5 944981 50.5
Vcells 988437 7.6 8388608 64.0 1762250 13.5

BTW - running summary() on line 80 summary( glm(returns[2:n] ~ returns[1:(n-1)]) ) works fine and does not result in a crash

hi @jaromf I can't replicate this error and it does indeed look like a memory issue. The memory that matters is the 8GB -- your working memory. Nothing in this file is big enough to fill that up so it must be that either (a) you have a bunch of other stuff in R using up working memory or (b) other applications are taking all the working memory. I'd suspect (a), so quit R studio and when you re-launch make sure that it is not loading any saved objects from previous sessions (i.e., make sure to not save your session).

Hi @mataddy I tried clearing as much RAM as possible, but still run into the issue. I posted the topic on a related thread in Rstudio Community. Ultimately, I may need to use a computer with more RAM. I'm thinking about setting up a powerful desktop computer and accessing it remotely as needed. https://community.rstudio.com/t/rstudio-desktop-on-a-chromebook-without-crouton-using-new-linux-beta-option/17393/9
