Bug: Slope Selector Plots incorrect

[js3110]

Description

The slope selector plots do not always match the NCA results, showing the wrong line of best fit or points included in lambda z. This is best noticed when comparing the output of one analyte vs multiple analytes for the same subject profile.

Looks like lamda.z.ix is being calculated incorrectly.
In addition, if user uses the table and selects 1:8 as manual slope, the selection includes 2,3,4,5,6,7 but not 1 and 8. Would be better if it was inclusive of the range the user inputs.

To reproduce

Run for one analyte
Run again for multiple analytes
Notice the plots have changed (should be the same for each one)
Notice that the points included in the plots don't always correspond to the lambda z points included in the NCA results.

Expected behaviour

• Slope plots should correspond exactly to the NCA results, and be the same no matter how many analytes / pcspec have been selected.

• Exclusions and inclusions should work fine, for both manual table adding or adding via interactive plots

• Inclusions should include the IX values the user inputs
