ggplot2 - R boxplot ggplot issues -

i new in r , trying graphics using ggplot , bit of reverse engineering. have info frame as:

> info experiments percentages 1 72.11538 2 90.62500 3 91.52542 4 b 94.81132 5 b 96.95122 6 b 98.95833 7 c 83.75000 8 c 84.84848 9 c 91.12903

because , b similar experiments following

data$experiments[data$experiments == "b"] = "a"

if now

ggplot(data, aes(x = experiments, y = percentages)) + geom_boxplot()

i 1 box a, 1 c still label b!

is there way of getting rid of b on x axis?

thanks lot help

i'm guessing experiments in data factor. if run str(data), imagine experiments factor 3 levels: a, b, , c. default, strings turned factors when info frame created.

the thought of factors represent set of possible values, if not possibilities in actual data. there 2 ways prepare this.

convert column string

data$experiments <- as.character(data$experiments)

or remove unused level in factor

data$experiments <- droplevels(data$experiment)

r ggplot2 boxplot

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...
