similar to: How to delete an entire row, if a specific colum has the value of "#VALUE!"

Hi, Hopefully someone can point me in the right direction on how I would go about solving the following. I have some data and need to find the column name of the maximum value in each row. This could be the data... > a <- data.frame(x = rnorm(4), y = rnorm(4), z = rnorm(4)) > a x y z 1 1.6534561 0.11523404 0.2261730 2 -1.2274320 -0.24096054 1.5096028

Hey guys, I've search a few threads about deleting a value from a vector, but no one has addressed this question so far.

I have data.frame's with IDs and multiple columns. B/c some of IDs showed up more than once, I need sum up colum values to creat a new dataframe with unique ids. I hope there are some cheaper ways of doing it... Because the dataframe is huge, it takes almost an hour to do the task. Thanks so much in advance!

Try the stringr package. This should work chemical=c("basic", "alkalin", "alkali", "acid", " ph ", "hss") chemical_match <- str_c(chemical, collapse = "|") chemical_match concept_df$match[str_detect(concept_df$concept, chemical_match)] <- "chemical" concept_df > concept_df concept match

Hi all, Imagine I have a matrix G with N rows and M columns So L=NxM is the number of different cells in my matrix. I want to create a column vector F whose size will be F(L,1) So the fisrt row in F is G(1,1) Second row in F is G(1,2) When we arrive to a point M the element M+1 will be G(2, 1) Element M+2 will be G(2,2) and so on. I´m trying but allways error.... Easy Example: G= 2 3 4

I need to select a line from the Zap group channel using the SIP Phone (not FXO and not FXS ports). ignorepat does not work? Also, what is the method to let the second dial tone has another tone frequency? Regards Bilal ---------------- No, ignorepat is for FXS ports (FXS ports use FXO signaling). Also, ignorepat does not apply to SIP phones, because SIP phones provide their own dialtone,

Dear List; How can I place a call via Zap/g1 (group) but need to determine the line (FXO port) that will go via it? Also, how it will be possible to assign an dedicated line (connected to FXO) to an button on the Polycom IP Phone or Broadtel IP Phone, so if user select that button then he will be sure that his outside call will be via that specific line.
