Metadata inferred about R objects or dynamic documents is stored in FeatureSet objects specific. Specific types of featuresets have specific additional metadata they contain, beyond the standard metadata inferred about all results, and represented by the core FeatureSet class.
user
character The user who submitted the result
regdate
POSIXct The date/time the result was recorded
analysispkg
list The R package associated with the result (because the working directory was within the package's directory structure).
uniqueid
character The uniqueid of the result
tags
character Additional tags associated with the result
analysisfile
character The .R file active when there result was recorded (RStudio IDE only)
rstudioproject
character The RStudio project active when the result was recorded (RStudio IDE only)
generatedin
character The uniqueid of the Rmd file the result was generated in, if applicable
code
character The code used to generate the result (by default, as captured by histry)
codeinfo
ScriptInfo the ScriptInfo for the code
sessioninfo
sinfoOrList The session info at the time the result was recorded
isplot
logical Whether the result is a plot
fsetklass
character The FeatureSet subclass for the result
trackrversion
character The exact version of the trackr package used to record the result.
clineargs
character The commandline arguments passed to R when starting the session the result was recorded from
resultURI
character The URI associated with the result, see featureset constructor documentation.
extrametadata
list Any extra metadata associated with the result.
titles
Title and subtitle of the plot object; a named list of the form list(main = "My title", sub = "My subtitle").
klass
character The R object class of the result
object
ANY The object itself, or NULL if the object is not available.
vars
character The variable names for a data.frame result
varclasses
character the variable classes for a data.frame result
varsummaries
list summaries for
object
ANY The object itself, or NULL if the object is not available.
data
A list of data.frames containing the variables and observations used in the plot.
varlabels
Variable labels of the plot object; a named list of the form list(x = "X axis label", y = "Y axis label", groups = list(...)). Note that non-empty labels are character vectors and may contain more than one entry.
annotation.text
Annotation text of the plot object.
vartypes
Variable types of the plot object; a named list of the form list(x = "numeric", y = "factor", ...).
grouping
Grouping information on the plot object; a named list.
coordsys
A character vector describing the coordinate system employed in the plot.
nobs
An integer representing the number of observations in the plotted data.
haslegend
A boolean indicating whether or not a legend is displayed in the plot.
tags
A character vector of user-defined tags.
code
R code to reproduce the plot, as a CodeDepends::Script object. May be empty.
codeinfo
Information about the R code to reproduce the plot, as a CodeDepends::ScriptInfo object. May be empty.
geom
A named list of parameters for geometric objects in each layer of the ggplot.
stat
A named list of parameters for statistical transforms in each layer of the ggplot.
position
A named list of positioning information in each layer of the ggplot.
num.layers
An integer representing the number of layers in the plot.
