Re: [R] Create Pie chart from .csv file
Im more than happy to use a barplot, but at this stage time is just so short I need something to show. I can find examples of plotting a line of numbers that has been manually typed into R, but Im missing something to do it from a CSV file. The name of my csv file is OutputFromDB. Would you know what I need to enter to get anything at all from this? Many thanks again, Michael Thomas Roth (geb.

Re: [R] Create Pie chart from .csv file
Ive found out a way around my problem. I was trying to plaot a histogram of strings, but I had to change it into integers. I ran an sql query on the original DB that I got the CSV file from and used COUNT to get the number of each unique item in a given column. I then used these numbers to create a histogram in R. It's a round about way of doing it, but it will have to suffice. Thanks to all for your tips. -- View this message in context: http://www.nabble.com/Create-Pie-chart-from-.csv-file-tp23387025p23410063.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

[R] Re ading from a Database
Hi all, I'm quite new to R and have limited experience. What Im trying to do is very important as it is part of my final year project; or more so the central idea behind it. I will be creating BibTex files to enter into a mySQL database. I then need to perform operations on this DB like 'return studies similar to x'. It's really just getting a start at this that I'm having trouble with and if anyone could offer any advice whatsoever I would be more than grateful. Many thanks. -- View this message in context: http://www.nabble.com/Reading-from-a-Database-tp22578072p22578072.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Re ading from a Database
Some of the simpler commands could surely be done using SQL-only queries, but thats too simple for my project. I need to create some more complex commands that would only be possible using R. Indeed if anyone has any suggestions for this, Id also appreciate that. Every little bit of information I get helps me finish college:-) Thanks for that info Ben and thanks to anyone else who shares some much needed insight with me.

This sounds much more like a database question than an R question. R has various interfaces (RmySQL, RODBC, etc) for interfaces to relational databases. Section 4 of the R data import/export manual gives quite a bit of detail. I think that if you need more information on SQL queries etc. you need to start with a local source (who is the advisor for your project?) good luck Ben Bolker __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. -- View this message in context: http://www.nabble.com/Reading-from-a-Database-tp22578072p22587990.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
