Jupyter Notebooks

  1. Hello, I am getting :- negative length vectors are not allowed While working on Jupyter R labs.cognitiveclass.ai(Cognitive lab Coursera))

    While I trying to retrieve data from database IBM Cloud using the below

    query = "SELECT COUNT(FDID) FROM FARMPRICES"
    sqlQuery(conn,query)

    I am getting following error:

    Error in odbcFetchRows(channel, max = max, buffsize = buffsize, nullstring = nullstring, : negative length vectors are not allowed
    Traceback:

    1. sqlQuery(conn, query)
    2. sqlGetResults(channel, errors = errors, ...)
    3. odbcFetchRows(channel, max = max, buffsize = buffsize, nullstring = nullstring, . believeNRows = believeNRows)

  3. Suppress "installing package ‘/home/notebook/R/library’"

    When installing a package, can we please suppress the output:

    Installing package into ‘/home/notebook/R/library’
    (as ‘lib’ is unspecified)
