Boxplot tables using ggplot2

Question

I am trying to build a boxplot graph with my data using "ggplot" in R, but I just can't do it. Can someone help me? The data is similar to the table below:

Paratio ShapeIdx FracD NNDis Core -3.00 1.22 0.14 2.71 7.49 -1.80 0.96 0.16 0.00 7.04 -3.00 1.10 0.13 2.71 6.85 -1.80 0.83 0.16 0.00 6.74 -0.18 0.41 0.27 0.00 6.24 -1.66 0.12 0.11 2.37 6.19 -1.07 0.06 0.14 0.00 6.11 -0.32 0.18 0.23 0.00 5.93 -1.16 0.32 0.15 0.00 5.59 -0.94 0.14 0.15 1.96 5.44 -1.13 0.31 0.16 0.00 5.42 -1.35 0.40 0.15 0.00 5.38 -0.53 0.25 0.20 2.08 5.32 -1.96 0.36 0.12 0.00 5.27 -1.09 0.07 0.13 0.00 5.22 -1.35 0.27 0.14 0.00 5.21 -1.25 0.21 0.14 0.00 5.19 -1.02 0.25 0.16 0.00 5.19 -1.28 0.22 0.14 0.00 5.11 -1.44 0.32 0.14 0.00 5.00 

And what I definitely want is the boxplot of each column, without any "column by column" relationship.

Answer 1

ggplot2 requires data in a specific format. Here you need x= and y= , where y will be the values ​​and x corresponding column identifiers. Use melt from reshape2 package to melt data to get data in this format, and then write.

 require(reshape2) ggplot(data = melt(dd), aes(x=variable, y=value)) + geom_boxplot(aes(fill=variable))
