Hi Guys Thank you for clearing something I dint know. Just wondering the reason of putting the word function(x) in the apply function when we have already declared stats function separately. I better understand how the arguments are passed. Thanks! -Abhi On Tue, Apr 27, 2010 at 2:46 PM, Erik I

Hi Henrique and Erik I still get a error. See below. apply(veh_drg_animal1[ ,c("readCount","gene_length")] ,1, stats, total=5500) Error in FUN(newX[, i], ...) : element 1 is empty; the part of the args list of '(' being evaluated was: (length_gene) stats<- function(count,length_ge

Re: [R] Passing values to a function when using apply

This is not a reproducible example. You might simply want: apply(veh_drg_animal1[, c("readCount", "gene_length")], 1, stats, arg2, arg3) But your "two parameters" from the data.frame are really going to be passed as one vector, and then within the stats function you can access them individua

[R] Passing values to a function when using apply

Hi All Slightly lost on how should I pass values to a function I am calling using apply. apply( veh_drg_animal1[ , c("readCount","gene_length")] ,1, stats() ) here stats is a custom function where I want to pass two parameters from data frame as shown and a third argument which is constant per
