r - Splitting axis labels with expressions -

i have plot long label containing look , want split on 2 lines. adding "\n" within look result not expected.

ylabel <- expression("a long label text , \n expression"*(alpha+beta) [ij]*" long label text , expression") curve(x^3 - 3*x, -2, 2, xlab=xlabel)

any help appreciated. thanks

here solution, relying on atop did @andrest in edit. note cannot utilize command character \n in expression, explains why using expression(paste("...\n", alpha[i], "....")) not produce desired output.

xlabel <- expression(atop("a long label text , expression", paste((alpha+beta)[ij], " long label ..."))) curve(x^3 - 3*x, -2, 2, sub=xlabel, xlab="")

note used sub instead of xlab avoid collision x tick marks.

r graph axis

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...
