Time-series slope over a range

MinutePlot^® and R on the same data. MinutePlot version 1.0.0; R 4.5.2.

Dataset

• series_slope (generated) — A generated series: x from 0 to 40, y flat, then rising linearly between x = 10 and x = 30, then flat again, with noise; fixed seed.
• Data file (the same format serves MinutePlot and R): series_slope.csv — one column per variable; paste it into the app, and keep it in the R script’s folder.

Setup

In MinutePlot:

• Workbench → Time-series slope over a range → paste series_slope.csv (x, y) → window from 10 to 30 → method linear regression → the run button.
• No sample-name column.

In R:

• Base R only; then run series_slope.R top to bottom (source it, or paste it into the console) with the R data file in the same folder.
• R 4.5.2 and the package versions in the page header; each script prints the versions it runs under.

The analysis:

• Selected window: x from 10 to 30 inclusive (21 points). MinutePlot fits an ordinary least-squares line to the points inside the window and reports the slope, intercept, standard error of the slope, R² and p. R reference: lm(y ~ x) on the subset.

Side-by-side results

Slope over the window x ∈ [10, 30]

Verdict

R script

series_slope.R — each script loads its data, prints its versions and the R-side tables shown above, in page order; no plotting.
