Nic Crane created ARROW-13887:
---------------------------------
Summary: [R] Various errors using schemas when reading in CSV file
Key: ARROW-13887
URL: https://issues.apache.org/jira/browse/ARROW-13887
Project: Apache Arrow
Issue Type: Bug
Components: R
Reporter: Nic Crane
While reporting another bug, I found an error while working with schemas. It's
not just this particular data type - try changing around the various data types
specified and similar errors occur. Unsure if this is at the R or C++ layer
{code:java}
share_data <- tibble::tibble(
company = c("AMZN", "GOOG", "BKNG", "TSLA"),
price = c(3463.12, 2884.38, 2300.46, 732.39),
date = rep(as.Date("2021-09-03"), 4)
)
readr::write_csv(share_data, file = "share_data.csv")
share_schema <- schema(
company = utf8(),
price = float64(),
date = date32()
)
read_csv_arrow("share_data.csv", schema = share_schema)
{code}
{code:java}
Error: Invalid: In CSV column #1: CSV conversion error to double: invalid value
'price'
