aou_collect {allofus}R Documentation

Collect a tbl object and convert integer64 columns to double

Description

If you connect to the All of Us database via aou_connect(), integer columns will be converted to the int64 class, which can represent 64-bit integers. This is safer than keeping as R's default integer class, because some of the values of the ID columns in All of Us are larger than R can handle as integers. However, this can make working with the local table more difficult in RStudio as a vector of values will not match the int64 class. This is not a problem in Jupyter notebooks, meaning that code that works on one platform may not work on another. A safe practice is to use aou_collect(), which works just like dplyr::collect() except that any integer values are converted to doubles. If this is not what you want, set convert_int64 = FALSE.

Usage

aou_collect(data, convert_int64 = TRUE, ...)

Arguments

data

A reference to a remote database table (or unexecuted query)

convert_int64

Do you want to convert integer values to doubles? Defaults to TRUE

...

Other arguments passed to dplyr::collect()

Details

[Experimental]

Value

a local dataframe

Examples



# returns 2 rows, as expected
dplyr::tbl(con, "concept") %>%
  dplyr::filter(concept_id %in% c(1112807, 4167538)) %>%
  aou_collect() %>%
  dplyr::filter(concept_id %in% c(1112807, 4167538))

default_collect <- tbl(con, "concept") %>%
  dplyr::filter(concept_id %in% c(1112807, 4167538)) %>%
  dplyr::collect()
# returns 2 rows in Jupyter and 0 in RStudio
dplyr::filter(default_collect, concept_id %in% c(1112807, 4167538))
