In terms of API the simplest but still usable would be to add new function, lets sayrowapply(we could catchapply(MARGIN=1)and redirect) which would be well optimized for common functions. It would be tricky to make it work for arbitrary R function, as we don't know if that functions ...
To find the row-wise frequency of zeros in an R data frame, we can use rowSums function for zero values by using the syntax − rowSums(“data_frame_name”==0) Consider the below data frame − Example Live Demo set.seed(189) x1<-sample(0:1,20,replace=TRUE) x2<-sample(0:5...
perform rowwise jobs in R and I was experimenting with various ideas on how to exploit the fact that the newly introduced functionacross()from{dplyr}creates tibbles on which one can easily apply a function. Romain came up withlay()as the better solution, making good use of{rlang}&{vctrs...

Bind each parameter to the first row of the array created in step 1 using SQLBindParameter(). For example, /* Parameter A */ rc = SQLBindParameter(hstmt, 1, SQL_PARAM_INPUT, SQL_C_LONG, SQL_INTEGER, 5, 0, &R[0].A, 0, &R.La); /* Parameter B */ rc = SQLBindParameter(...

A novel method of digit shifting in a bidirectional shift register is described which provides substantial saving of components in terms of gates. In this method only the bits occupying the 1-position of the 8-4-2-1 code can shift in either direction. Bits of the same digit position are ...
In addition, some applications of theL_rconvergence, weak and strong laws of large numbers to nonparametric regression models based on END errors are provided. The results obtained in the paper generalize or improve some corresponding ones for negatively associated random variables and negatively ...
