format

问题 I'd like to allign a string to the right but have its beginning be truncated instead of its end.

问题 What is the best way to convert various audio formats to PCM? For example: mp3, evrc, ogg vox. Is there a library out there that will allow me to implement this relatively easily? EDIT: I guess my initial question wasn't really what I needed. Most of the libs I have found are file converters. What I need is a block converter, where I pass in a 1Kb block of vox data and it returns its converted PCM block. Of course I’ll have to tell the converter what type of data it is and various pieces of

问题 Using the iris data, we make a table with the tables package: library(tables) table <- tabular( (Sepal.Length+Sepal.Width) ~ Format(format(digits=2))*(mean + sd), data=iris ) With the Hmisc package, we would add the caption with the latex function like this: latex(table, caption="My table") But that does not work with the tables package, because it defines an S3 method, latex.tabular .
