New to R studio. Need to get out the throughput time through a plot, but getting an error in return.

Error I'm getting: Error in plot.window(...) : need finite 'ylim' values

Some recommendations for what I can add?

```
throughput_time_qcc <- qcc(log(ntp_casestats_mr$throughput_time), type = "xbar.one",
labels = ntp_casestats_mr$case_id, plot = FALSE)
plot(throughput_time_qcc, title = "X (individual measurements) chart for throughput time (hours)",
xlab = "Case ID", ylab = "log (throughput time)", digits = 2, )
process.capability(throughput_time_qcc, spec.limits = c(NA, log(100)), nsigmas=3, digits = 2)
```
