Description Usage Arguments Value Note Examples

Prints and returns Pearson's correlation between each variable and each measure listed. Can pass in a dataset from create_dataset, or function calls create_dataset itself.

1 | ```
correlation(dataset = NA, person, variables, measures, time_var = NA)
``` |

`dataset` |
dataset from create_dataset that contains all variables and measures of interest |

`person` |
an instantiated Person object |

`variables` |
list of variables in person of interest, with structure list(source1 = c(var1, var2), source2 = c(var3, var4)) where source is a source of data as defined in a Person object, and var1 and var2 are variables from source1, while var3 and var4 are variables from source2 |

`measures` |
list of measures in person of interest, with structure list(source1 = c(var1, var2), source2 = c(var3, var4)) where source is a source of data as defined in a Person object, and var1 and var2 are variables from source1, while var3 and var4 are variables from source2 |

`time_var` |
the time variable that variables and measures are observed in (time, date, or datetime) - only needed if dataset is not passed in |

Pearson's correlation between each variable and each measure

'correlation' uses "pairwise.complete.obs", which only computes the correlation between all complete pairs of observations.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 | ```
data(EX)
dataset <- create_dataset(person = EX,
all_variables = list("fitbit_daily" = c("sleepDuration",
"steps")),
time_var = c("date"))
correlation_df <- correlation(dataset, person = EX,
variables = list("fitbit_daily" =
c("sleepDuration")),
measures = list("fitbit_daily" = c("steps")),
time_var = "date")
``` |

```
