[R] boxplot
Hi, I try to boxplot following data on the subset of (V1,V3,V5,V7) and (V2,V4,V6,V8) V1 V2 V3 V4 V5 V6 V7 V8 24 6 712 33 43 53 how can I use boxplot function to plot it? thanks, William __ 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] Is it possible to start R-GUI in a windowed state under Windows OS
Is it possible to start R-Gui in a windowed state under windows? (I am running Windows 7 and Vista) I have the set the property for R icon to normal window option, but that has no effect.

[R] Efficient way to Calculate the squared distances for a set of vectors to a fixed vector
I am pretty new to R. So this may be an easy question for most of you. I would like to calculate the squared distances of a large set (let's say 2) of vectors (let's say dimension of 5) to a fixed vector. Say I have a data frame MY_VECTORS with 2 rows and 5 columns, and one 5x1 vector y. I would like to efficiently calculate the squared distances between each of the 2 vectors in MY_VECTORS and y. The squared distance between two vectors x and y can be calculated: distance - crossprod(x-y) Without looping, what is the efficient code to achieve this?
