[R] Dividing rows in groups

Hi I have two data frames as shown below (second one is obtained by aggregating rows of similar IDs in df1.). They both have similar number of columns but rows of df2 are lesser than rows of df1. df1: ID A B 1 1 2 1 0 3 2

Re: [R] Data Frame Column Name Attribute

You could use transform() instead of [[<- to add columns to your data.frame so the new columns get transformed they way they do when given to the data.frame function itself. E.g., > dd <- data.frame(X=1:5, Y=11:15) > str(transform(dd, Z=matrix(X+Y,ncol=1,dimnames=list(NULL, "NewZ"

I am attempting to add a calculated column to a data frame. Basically, adding a column called "newcol2" which are the stock closing prices from 1 day to the next. The one little hang up is the name of the column. There seems to be an additional data column name included in the attributes

Re: [R] subset by multiple letters condition

This is quite a different question. I suggest you start a new post with a new subject line for this. And I suggest you include code for an example plot that you want to use. Otherwise, you might look here for some ideas on how to control colors in a scatter plot using base r,

Hi Georg, The " around Kunden$* looks unintentional to me. Second: haveyou considered using a long table? Then you would fill a known set of columns. Third if you must have columns based on year I believe df[[a.column.name]] will work. Best Ulrik schrieb am Sa., 23. Apr.

Re: [R] Creating variables on the fly

The direct answer to your question is to look at ?get and ? assign. The R-ish answer to your question is to store the data as elements of a list rather than separate files and use lapply() instead. Sarah On Friday, April 22, 2016, wrote: > Hi all, > > I would like to use a
