Hi Malvika, What David means is that we don't do people's homework for them. Have a look at "An Introduction to R" that comes with the R distribution, particularly about sequences and vectorization. Jim On Fri, Jan 6, 2017 at 7:40 AM, Malvika Marathe wrote: > Can you please

Sorry for the emails. I just checked and the problem is still there. Is there a proper way to reformat the decimal places, such as three or four decimal places? Thanks. If maintain four decimal places, the numbers are: 1.2000, 1.3100, 1.4000, etc. On Thu, Jan 5, 2017 at 10:46 PM, lily li

[R] About concatenating strings

Hi R users, I'm trying to concatenate two strings, while each string has numbers. For example, strings1 = c(1.2, 1.31, 1.4, 1.51, etc), strings2= c(2.1, 2.22, 2.3, 2.44, etc). I want to have all decimals for the two strings, such as: strings1= c(1.20, 1.31, 1.40, 1.51, etc), string2 = c(2.10,

Re: [R] Generating a Special Histogram

Here's a different approach using barplot() to draw the boxes. The first line in the function sorts the values so that they are printed from lowest to highest on the histogram. If you want them in the original sequence, comment this line out. It also assumes you want intervals of 10:
