您的if语句正在查看逻辑向量，但为所有行返回一个值，例如：df[,2]是整列：0.50 0.11 0.23 0....
一种方法可以是使用tidyr来旋转，并使用dplyr来满足以下条件：
您可以尝试：
("Less than 100.")+ } else if (jk < 200) {+ print("Less than 200.")+ } else if (jk < 300) {+ print("Less than 300.")+ }[1] "Less than 200.">> # Multiple conditions satisfied. No else statements.> if(jk < 100){+ print("Less than 100.")+ }> if (jk < 200) ...
Else-if statements in R In some cases, you may want to checkmultiple conditions. For this, you can use the “else if” keyword. If you are familiar withif-else statements in Python, you may already know the else-if statement from R as the keyword “elif”. ...

} else { print ("Team B will make the playoffs") } "Team B will make the playoffs" Using the for loop to run our code Now that we’ve used an if-else statement to display the results of one match, what if we wanted to find the results ofmultiplematches? Let’s say we have a...
II.1. Saliency maps(gradient and perturbation based methods) Goal: compute relative importance of each token in the input -- if you change or remove the token, how much is the prediction affected? II.1.1 Saliency maps via input gradients. Straightforward. For NLP, this is the "derivative of...
If the management nodes are deployed in cluster mode, and the management node has been restarted for multiple times within 30 minutes, which causes the master database instance of the node to become abnormal, so you cannot log in to the management plane. If the database nodes of the product...
