## Description

Trying to run the CTL Maps feature in the collections page as described in
=> /issues/genenetwork2/broken-collections-feature

We get an error in the results page of the form:

```
{'error': '{\'code\': 1, \'output\': \'Loading required package: MASS\\nLoading required package: parallel\\nLoading required package: qtl\\nThere were 13 warnings (use warnings() to see them)\\nError in xspline(x, y, shape = 0, lwd = lwd, border = col, lty = lty, : \\n invalid value specified for graphical parameter "lwd"\\nCalls: ctl.lineplot -> draw.spline -> xspline\\nExecution halted\\n\'}'}
```

on the CLI the same error is rendered:
```
Loading required package: MASS
Loading required package: parallel
Loading required package: qtl
There were 13 warnings (use warnings() to see them)
Error in xspline(x, y, shape = 0, lwd = lwd, border = col, lty = lty,  : 
  invalid value specified for graphical parameter "lwd"
Calls: ctl.lineplot -> draw.spline -> xspline
Execution halted
```

On my local development machine, the command run was
```
Rscript /home/frederick/genenetwork/genenetwork3/scripts/ctl_analysis.R /tmp/01828928-26e6-4cad-bbc8-59fd7a7977de.json
```

Troubleshooting a while, I suspect
=> https://github.com/genenetwork/genenetwork3/blob/27d9c9d6ef7f37066fc63af3d6585bf18aeec925/scripts/ctl_analysis.R#L79-L80 this is the offending code.

=> https://cran.r-project.org/web/packages/ctl/ctl.pdf The manual for the ctl library
indicates that our call above might be okay, which might mean something changed in the dependencies that the ctl library used.
