I have a file of data where each line is a series of name-value pairs, but where the names are not necessarily the same from line to line, e.g. a=1,b=2,d=5 b=4,c=3,e=3 a=5,d=1 I would like to create a data frame which lines up the data in the corresponding columns. In this case, this would be data.frame( a = (1, NA, 4), b = (2, 4, NA), c = (NA, 3, NA), d = (5, NA, 1), e = (NA, 3,

The setup: I have a data frame where one column is in list mode, and each entry contains a vector of varying length. I want to expand this into a data frame with one row for each member of the list-mode column (the other values being replicated) For example, an example input and the desired output would be: input <- data.frame(site = 1:6, sector =

I have a dataframe df with two columns x and y. I want to count the number of times a unique x, y combination occurs. For example x<- c(1,2,3,4,5,1,2,3,4) y<- c(1,2,3,4,5,1,2,4,1) df<-as.data.frame(cbind(x, y)) #what is the correct way to use ddply for this example? ddply(df, c('x','y', summarize, ??) #desired output -- format and order doesn't matter # (x, y)
