It seems to me that the reshape package should do the job,
library(reshape) # note that you need to fix the method to melt lists
in the current version ( passing ... to the method for data.frames, as
discussed here last week)
cast(data=melt(dat), fun.aggregate = function(.x) rle(.x)$length[
### Example Data
dat <-list()
set.seed(1)
dat[[1]] <- data.frame(matrix( rbinom(40, 1, .8),nrow=5))
dat[[2]] <- data.frame(matrix( rbinom(40, 1, .8),nrow=5))
Code
x<-sapply(dat,"[",3)#Extracting the vector
y<-lapply(x,rle) #Counting the sequences which is returned as a list
z<-sapp
Hello everybody,
I have problem with a lapply command, which rather proves that I don't
fully understand it.
I want to extract from a list that consists of dataframes, the length
of the first sequences from a given variable (its part of a simulation
exercises).
Below is code which does the job, b
