r - Getting Sweave code chunks to stay inside page margins? -

sometimes create r code chunk (in sweave) longer margins of page. there way forcefulness "go next line" 1 time happens?

here simple illustration of happening:

\documentclass[a4paper]{article} \usepackage{sweave} \defineverbatimenvironment{sinput}{verbatim} {xleftmargin=2em, frame=single} \defineverbatimenvironment{soutput}{verbatim}{xleftmargin=2em, frame=single} \title{sweave boxes} \begin{document} \maketitle <<echo=false>>= options(width=60) @ here illustration of code chunk followed output chunk, both enclosed in boxes. <<>>= print(rnorm(99)) @ <<>>= print("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa") @ \end{document}

this hard , extreme case, because not have spaces among a's, latex may not able wrap words. if have spaces, knitr able produce output long lines wrapped tidy=true, highlight=true (so sweave, think, if set keep.source=false).

r latex tex sweave

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
