plotly_spec: Interactive plots for OpenSpecy objects

Description

These functions generate heatmaps, spectral plots, and interactive plots for OpenSpecy data.

Usage

plotly_spec(x, ...)
# S3 method for default
plotly_spec(x, ...)
# S3 method for OpenSpecy
plotly_spec(
  x,
  x2 = NULL,
  line = list(color = "rgb(255, 255, 255)"),
  line2 = list(dash = "dot", color = "rgb(255,0,0)"),
  font = list(color = "#FFFFFF"),
  plot_bgcolor = "rgba(17, 0, 73, 0)",
  paper_bgcolor = "rgb(0, 0, 0)",
  showlegend = FALSE,
  make_rel = TRUE,
  ...
)
heatmap_spec(x, ...)
# S3 method for default
heatmap_spec(x, ...)
# S3 method for OpenSpecy
heatmap_spec(
  x,
  z = NULL,
  sn = NULL,
  cor = NULL,
  min_sn = NULL,
  min_cor = NULL,
  select = NULL,
  font = list(color = "#FFFFFF"),
  plot_bgcolor = "rgba(17, 0, 73, 0)",
  paper_bgcolor = "rgb(0, 0, 0)",
  colorscale = "Viridis",
  showlegend = FALSE,
  type = "interactive",
  ...
)
interactive_plot(x, ...)
# S3 method for default
interactive_plot(x, ...)
# S3 method for OpenSpecy
interactive_plot(
  x,
  x2 = NULL,
  select = NULL,
  line = list(color = "rgb(255, 255, 255)"),
  line2 = list(dash = "dot", color = "rgb(255,0,0)"),
  font = list(color = "#FFFFFF"),
  plot_bgcolor = "rgba(17, 0, 73, 0)",
  paper_bgcolor = "rgb(0, 0, 0)",
  colorscale = "Viridis",
  ...
)

Value

A plotly heatmap object displaying the OpenSpecy data. A subplot containing the heatmap and spectra plot. A plotly object displaying the spectra from the OpenSpecy object(s).

Arguments

x

an OpenSpecy object containing metadata and spectral data for the first group.

x2

an optional second OpenSpecy object containing metadata and spectral data for the second group.

line

list; line parameter for x; passed to add_trace().

line2

list; line parameter for x2; passed to

font

list; passed to layout().

plot_bgcolor

color value; passed to layout().

paper_bgcolor

color value; passed to layout().

showlegend

whether to show the legend passed to

make_rel

logical, whether to make the spectra relative or use the raw values

z

optional numeric vector specifying the intensity values for the heatmap. If not provided, the function will use the intensity values from the OpenSpecy object.

sn

optional numeric value specifying the signal-to-noise ratio threshold. If provided along with min_sn, regions with SNR below the threshold will be excluded from the heatmap.

cor

optional numeric value specifying the correlation threshold. If provided along with min_cor, regions with correlation below the threshold will be excluded from the heatmap.

min_sn

optional numeric value specifying the minimum signal-to-noise ratio for inclusion in the heatmap. Regions with SNR below this threshold will be excluded.

min_cor

optional numeric value specifying the minimum correlation for inclusion in the heatmap. Regions with correlation below this threshold will be excluded.

select

optional index of the selected spectrum to highlight on the heatmap.

colorscale

colorscale passed to add_trace() can be an array or one of "Blackbody", "Bluered", "Blues", "Cividis", "Earth", "Electric", "Greens", "Greys", "Hot", "Jet", "Picnic", "Portland", "Rainbow", "RdBu", "Reds", "Viridis", "YlGnBu", "YlOrRd".

type

specification for plot type either interactive or static plot_ly().

...

further arguments passed to plot_ly().
