    Two column for LaTeX from Pandoc.

    Add twocolumn and replace longtable with supertabular.

    \documentclass[twocolumn]{article}
    ...
    \usepackage{supertabular}
    ...
    \begin{supertabular}[c]{@{}lll@{}}
    ...
    \end{supertabular}
    

    To make a figure span over two columns, use figure*.

    \begin{figure*}[htbp]

    Change the order of discrete axis.

    Generate a factor with reversed levels or use a new ggplot2 option.

    Examples.

    df$X1 = with(df, factor(X1, levels = rev(levels(X1))))

    1. Reverse the order of a discrete-valued axis
    2. Get the levels of the factor
    flevels <- levels(PlantGrowth$group)
    1. "ctrl" "trt1" "trt2"
    2. Reverse the order
    flevels <- rev(flevels)
    1. "trt2" "trt1" "ctrl"
    bp + scale_x_discrete(limits=flevels)

    Selecting objects in Inkscape.

    Method 1. Hold down Shift key and use the mouse to click on each object to be selected.

    Method 2. Select by colour.

    • CTRL F for a new menu panel.

    -drag colour selection from lower colour bar and drop into Style in the new menu panel as shown below.

    • click on Find.
    • All items of the selected colour are now highlighted.

    Also you may notice the colour changes to a number in the style box.

    Method 3. Hold down the Alt key on your keyboard and drag mouse through items to be selected.
    When Alt is held down a red line will be visible, making it easier to select the chosen path.

    Nested Tmux command.

    Screen (vim + gnu screen/tmux) is a great tool for vim that split the pane and send vim buffer to
    another pane. (Link: http://www.vim.org/scripts/script.php?script_id=2711)

    However, when used the plugin in tmux session, the tmux sessions are nested then the command
    is not working properly. Then setting a send prefix in .tmuxrc will solve the nested problem.

    Command Sequence for Nested Tmux Sessions

    Often I’ll run a multiplexer inside another multiplexer and need a command sequence to send things to the inner session. In Screen, this could be accomplished using C-a a . This doesn’t work out of the box in tmux, but can be fixed with a little configuration.

    slopegraph

    Slopegraph in R. Slopegraph shows the change of the quantity or rank.

    Beautiful slopegraph example. http://www.drewconway.com/zia/

    Theory of slopegraph. http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0003nk

    An R and ggplot2 code example of slopegraph https://github.com/leondutoit/slopegraph/blob/master/slopegraph.

    R Example code.

    Generate sample data

    a <- data.frame(go = LETTERS[1:10], enrich = runif(10, 0, 10))
    b <- data.frame(go = LETTERS[1:10], enrich = runif(10, 0, 10))
    a <- cbind(a, status ='before')
    
    b <- cbind(b, status = 'after')
    ab.melt <- rbind(a, b)
    

    Add an offset column for label positioning

    ab.melt <- transform(ab.melt, offset = c(rep(2, times = 10), rep(-2, times = 10)))
    
    library(ggplot2)
    ggplot(data = ab.melt, aes(x = status, y = enrich)) + geom_line(aes(group = go, colour = go)) + geom_text(aes(label = go, hjust = offset, colour = factor(go)))
