These commands (after the first one) work in the ed editor. ed editor is used in the RStudio server shell.

In this example the script will run every 0 hours, 30 minutes, see Ubuntu: How do I set up a CRON job for other options.

By default, LaTex tables are very tight:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
usepackage{booktabs} begin{table}[] centering caption{My caption} label{my-label} begin{tabular}{@{}lll@{}} toprule Rows & Column 1 & Column 2 midrule Row 1 & 1234 & 2345 Row 2 & 3456 & 4567 Row 3 & 5678 & 6789 Row 4 & 7890 & 8901 Row 5 & 9012 & 10000 bottomrule end{tabular} end{table} |
Adding this to the document preamble will add space between the rows:
1 2 |
renewcommand{arraystretch}{1.7} |
And this command can be used to add space between rows manually:
1 2 |
vspace{1cm} |

One picture says more than a thousand words. You have what is one the left, and you want what is on the right.

my_matrix = matrix(c(1, 2, 3, 4, 5, 6, 7, 8, 9), nrow=3) #matrix is a 2D array, this next row creates a third dimension, #duplicating the data my_array = array(my_matrix, dim = c(3,3,2)) |
There are a few different ways to do this, but by far the cleanest and quickest way is to just select the rows and columns multiple times, by replicating row and column numbers (instead of actually replicating each element):
1 2 3 4 5 6 |
#2D: increased_matrix = my_matrix[rep(1:nrow(my_matrix), each=3), rep(1:ncol(my_matrix, each=3)] #3D (same really, just one extra comma for the third dimension): increased_array = my_array[rep(1:nrow(my_array), each=3), rep(1:ncol(my_array, each=3), ] |
Note that by default, in rep(something, n) the n is times so equivalent to rep(something, times=n), but in this case we need to use each instead of times.

I’ve recently started using ggplot2 in addition to lattice (see this post that I made a while ago, explaining how I got into using lattice in the first place). Hint: when using ggplot2, you’ll need to use of the reshape2 package (also written by the amazing Hadley Wickham) to get your data into a form that ggplot2 works best with. Another thing that you’ll want to think about when using ggplo2 is factor levels. This post will show how to (and also how not to) rearrange factor levels in R.
Let’s create a quick barplot with strings as x labels.
1 2 3 4 5 6 7 8 9 10 |
library(ggplot2) #create dummy data a = paste('my', 1:11) b = 1:11 df = data.frame(a, b) df qplot(a, b, data=df, geom='bar', stat='identity') + theme(axis.text=element_text(size=16, angle=45)) |
As df$a is an array of strings, R sets the factor levels alphabetically: my 1, my 10, my 11, my 2…which is not what we want, so let’s rearrange factor levels:
1 2 3 4 5 |
df$a = factor(df$a, levels = paste('my', 1:11)) df$a qplot(a, b, data=df, geom='bar', stat='identity') + theme(axis.text=element_text(size=16, angle=45)) |
And finally, the wrong way to rearrange factor levels would be by using the levels() function:
1 2 3 4 5 |
df = data.frame(a, b) levels(df$a) = paste('my', 1:11) qplot(a, b, data=df, geom='bar', stat='identity') + theme(axis.text=element_text(size=16, angle=45)) |
So be careful – if your data is not as obvious as this example and you are a bit new to factors and levels, you might end up plotting wrong results (like on the last example, “my 2” and “my 3” were plotted with the values 10 and 11).
