Correct the documented facet sizing.
The facet branch in .conditionLayoutSpecs() uses facet_grid(..., scales = "free_x") without space = "free_x", so panels retain equal widths. Document free x scales with equal-width panels.

Keep file-output documentation in dataProcessPlots().
The three private helpers return plot objects. Their isPlotly descriptions also claim that a PDF is automatically created and expose address, which these helpers do not accept.

Forward caller geometry to ggplotly().
Line 668 always creates an 800×600 Plotly figure. A caller that sets another width or height gets the wrong HTML geometry. The condition-label calculation can also select a layout for a width that the Plotly figure does not use.
Add width and height parameters to .convertGgplot2Plotly(). Pass them from every dataProcessPlots() conversion call.

Motivation and Context
dataProcessPlots()produced two rendering failures on Profile and QC plots.Oversized feature legend. ggplot2 allocates legend space before panel space, and
features per protein are unbounded.
DIARawData's 149-feature protein rendered as afull page of legend with no data panel on it at all. On the Plotly path the legend was
silently truncated to roughly ten entries — the omission was never stated.
Overlapping condition labels. Condition names are drawn inside the panel by
geom_text(), and conditions tile the panel evenly, so each name getspanel_width / n_conditionsof room regardless of how many runs it contains. Longnames exceed that slot and collide.
A narrowing of the ticket's premise, worth flagging for review: the ticket named
two triggers — few samples per condition, and long condition names. Only the second
reproduces. Measured as label width over available slot width, every good case sits at
≤ 0.75 and every overlapping case at ≥ 2.36;
msstats_demo.csvwith 8 conditions over2 facets renders cleanly at 0.75. Runs per condition do not affect label spacing at
all, which is why the heuristic here measures name width and never a sample count. No
separate issue was filed for the narrowing.
Solution. Past
max.legend.entries(default 30) the per-feature colour key isdropped and the feature count moves into the plot title, so the loss is stated rather
than silent. Where a condition name is wider than its slot, the condition becomes a
facet_grid()strip with the name wrapped to fit — ggplot2 then reserves a band forit, so collision with the data and clipping at the panel edge stop being possible
rather than being mitigated. Plots whose labels already fit render identically to
before.
Changes
Legend (
R/utils_dataprocess_plots.R,R/dataProcessPlots.R)max.legend.entriesargument (default 30). A protein above the cap is drawnwithout the feature legend and its title gains a note:
"P12345 (149 features; legend omitted)".Infalways draws the legend. Thecomparison is strict, so 30 entries keep it and 31 lose it.
part goes.
legend.position(default"top") andlegend.ncol(defaultNULL→ threecolumns, the previous hard-coded value).
legend.positionis threaded through.convertGgplot2Plotly()so it is honoured inthe Plotly output, not just the PDF. Callers that do not pass it get the historical
placement unchanged.
.convertGgplot2Plotly()now passeswidth/heighttoggplotly()rather than toplotly::layout(), where they are deprecated.guides(color = FALSE)withguides(color = "none").Condition labels (
R/utils_dataprocess_plots.R).layoutConditionLabels()decides between the in-panel layout and facet strips,and sizes the strip font and wrap width to the room a strip actually has.
.wrapConditionLabels()turns_and.into break opportunities forstrwrap()and removes the injected spaces afterwards, so wrapped lines rejoin tothe original name at any width.
.conditionLayoutSpecs()returns the facet/vline/text/strip pieces that differbetween the two layouts, so
.makeProfilePlot(),.makeSummaryProfilePlot()and.makeQCPlot()keep a single pipeline — addingNULLis a no-op in ggplot2.condition.label.adjustargument (defaultTRUE);FALSEreproduces theprevious layout exactly. A non-zero
text.angleis treated as a deliberate choice bythe caller and also leaves the layout alone.
GROUPthrough tocombined(mapped back fromthe run/condition table) so it can facet on condition.
Docs (
man/,inst/NEWS.rd).Rdfiles viadevtools::document().text.angleaffects the ggplot2 output only —ggplotly()does notcarry text rotation through, so it has never had an effect when
isPlotly = TRUE.plan/(local working notes) added to.gitignoreand.Rbuildignore.Two implementation choices reviewers may want to push on
nchar, not measured.grid::stringWidth()is exactbut needs an open graphics device, which is not available while the plot is being
built — measuring would make the result device-dependent and the function untestable.
0.53 em per character is calibrated against
graphics::strwidth()on thereproduction data and lands within ~7%.
guide_axis(n.dodge=, check.overlap=)would be the ggplot-native fix and wasrejected:
ggplotly()handles it poorly, and MSstatsShiny renders throughggplotly(). For the same reason rotation andggrepelwere rejected; shrinking thefont enough to fit 30-character names reaches ~2pt.
features per protein, p90 37, max 107), a cap of 30 leaves ~86% of proteins
untouched; 40 leaves ~91%, 50 leaves ~95%. At the boundary the legend is not yet
doing harm —
DDARawData's "rabbit" (31 features) renders a readable panel withits legend — so 40 or 50 would also be defensible. Happy to raise it; it is a
one-line change and nothing else depends on the value.
