vascr_subset(
  data.df,
  time = NULL,
  unit = NULL,
  well = NULL,
  value_greater_than = NULL,
  value_less_than = NULL,
  value_equal_to = NULL,
  sample_contains = NULL,
  sample_not_contains = NULL,
  sample_equal_to = NULL,
  variable_set = NULL,
  variable_unset = NULL,
  variable_equal_to = NULL,
  variable_not_equal_to = NULL,
  variable_greater_than = NULL,
  variable_less_than = NULL,
  include_vehicle = TRUE,
  frequency = NULL,
  experiment = NULL,
  instrument = NULL,
  max_deviation = NULL,
  subsample = NULL,
  return_lists = FALSE,
  sampleid = NULL,
  remake_name = TRUE
)

Arguments

data.df	Vascr dataset to subset
time	Specified times. Individual values in a list will be subset out. If vectors are present in the list, values between the two most extreme values will be returned.
unit	Units to subset. These are checked for integrity against possible units and the dataset itself
well	Wells to select
value_greater_than	Select lines where the value is greater than a certain value
value_less_than	Select lines where the value is less than a certain value
value_equal_to	Select lines where the value is equal to a certain value
sample_contains	Return lines where the sample contains a particular value
sample_not_contains	Return lines where theh sample does not contain particular values
sample_equal_to	Return lines when the sample exactly matches a particular string
variable_set	Vector of variables. Lines will be returned if a variable is set.
variable_unset	Vector of variables. Lines will be returned if a variable is not set.
variable_equal_to	Vector of pairs of variables and values. Rows will be returned where each variable matches the value following it.
variable_not_equal_to	Vector of pairs of variables and values. Rows will be returned where each selected variable does not match the value following it.
variable_greater_than	Vector of pairs of variables and values. Rows will be returned where each selected variable is larger than value following it.
variable_less_than	Vector of pairs of variables and values. Rows will be returned where each selected variable is less than value following it.
include_vehicle	Should all relevant vehicle control wells be included in the dataset.
frequency	Frequencies to include in the dataset.
experiment	Experiments to include in the dataset. Can be addressed either by name, or by the numerical order that they were loaded into vascr_combine in
instrument	Which instruments to include values from
max_deviation	Maximum deviation to allow between replicates
subsample	Frequency values shoud be subsampled to
return_lists	Return lists of the variables to select rather than the subset data set
sampleid	List of ID's to be used. Sample names will be re-ordered accordingly for display.
remake_name	Should the name be re-formatted

Value

The subset dataset, based on the values selected

Examples

# vascr_subset(growth.df)
# vascr_subset(growth.df, time = 40)
# vascr_subset(growth.df, time = NULL)
 
# vascr_subset(growth.df, unit = "Rb")
# vascr_subset(growth.df, unit = "R")
# vascr_subset(growth.df, well = "A1")
# vascr_subset(growth.df, value_less_than = 100)
# vascr_subset(growth.df, max_deviation = 10)

# vascr_subset(growth.df, time = c(5,20))

vascr_subset(growth.df, unit = "Rb")
