similar to: Creating a sparse matrix from a file

I?ve got an Excel workbook with about 30 worksheets. Each worksheet has 10000 rows of data over 30 columns. I?d like to read the data from each worksheet into a dataframe or matrix in R for processing. Normally, I use read.csv when interacting with Excel but I?d rather manipulate a multisheet workbook directly than set about splitting the original workbook and saving down each part as a csv.

Hello,? I have a data set similar to below and I wanted to keep the observations after the first occurrence of these department: "B", "D", "F".For example for ID=2, the observation with deps=B and anything after will be kept in the data. For ID=3, observations with deps=D and anything after will be included. Subject<- c("2", "2", "2",

Dear list, We have a number of files containing similarly structured data: file1: A B C 1 2 3 4 5 6 file2: A B C 7 8 9 10 11 12 ... etc My part of R receives all these data as an array: 1,2,3... 12 together with info about dimensions (row,col,fileN) . ( Converting the data into 3D cannot simply done by: array(x, c(2,3,2)) because breaks the structure (e.g. 1,3,5 is type mismatch)

Hi Jim,? Thank you tons for your help. The code worked perfectly :)?Best,Farnoosh On Wednesday, March 30, 2016 1:13 AM, Jim Lemon <drjimlemon at gmail.com> wrote: Hi Farnoosh, Despite my deep suspicion that this answer will solve a useless problem, try this: last_subject<-0 keep_deps<-c("B","D","F") keep_rows<-NULL for(rowindex in

The following examples are confusing to me. It is OK, to assigned NULL to one element in a list. The result is still a list. However, a list of NULL's are reduced to NULL. I don't understand how this conversion occurs. Could somebody let me know what is going on? > X=matrix(1:8, nr=4) > apply(X,1, function(x) {if(x[[1]]==3){NULL}else{x[[1]]}}) [[1]] [1] 1 [[2]] [1] 2 [[3]] NULL

Hey all, Does anyone know how we can get train set and test set for each fold of 5 fold cross validation in Caret package? Imagine if I want to do cross validation by random forest method, I do the following in Caret: set.seed(12) train_control <- trainControl(method="cv", number=5,savePredictions = TRUE) rfmodel <- train(Species~., data=iris, trControl=train_control,
