Figure 2: for-loop with break Function. As shown in Figure 2, the loop stops (or“breaks”) when our running index i is equal to the value 4. For that reason, R returns only three sentences. Example 2:nextwithin for-loop The next statement can be useful, in case we want to contin...
mapply is a multivariate apply of sorts which applies a function in parallel over a set of arguments. > str(mapply) function (FUN, ..., MoreArgs = NULL, SIMPLIFY = TRUE,USE.NAMES = TRUE) FUN is a function to apply ... contains arguments to apply over MoreArgs is a list of other ...
for (i in 1: nrow(matrix)) { row_sum[i] <- sum(matrix[i, ]) # 对每一行求和 } return(row_sum) } 1. 2. 3. 4. 5. 6. 7. 8. 使用sapply()可以这样简化代码: func2 <- function(matrix) { return(sapply(1: nrow(matrix), function(i) { return(sum(matrix[i, ])) })) } ...
相对于其它检测R-loop的方法,MapR具有以下几个特点:1)MapR的整个实验过程是在细胞内,并且利用MNase对核酸序列进行切割,能够检测到一些相对弱的或是瞬时形成的R-loop;2)MapR不依赖S9.6抗体,不需要构建稳定表达RNaseH的细胞系,整个实验过程只需要一天时间...

Function The loop-free-alternate command enables IS-IS Auto FRR to calculate loop-free backup routes using the loop-free alternate (LFA) algorithm. The undo loop-free-alternate command disables IS-IS Auto FRR from calculating loop-free backup routes using the LFA algorithm. By default, IS-IS...

OSPFv3 can use the routing loop detection function to detect routing loops. When OSPFv3 is configured to import routes or distribute default routes, routing loop detection can be deployed to proactively detect whether routing loops exist in the topology and whether the routing loop prevention ...
