如何将grepl应用于数据框

Question

解决方案：

@docendodiscimus发表：“尝试在模式上进行一个sapply循环：

sapply(df_triggers$trigger, grepl, df_sen$sentence)"

初步问题：

我想将grepl用于定义为数据帧的多个模式。 df_sen显示为

sentence
"She would like to go there"
"I had it few days ago"
"We have spent few millions"

df_triggers显示如下：

trigger
few days
few millions

我想创建一个矩阵，其中句子x触发，并且在交叉点上查看1是否在句子中找到触发器，如果​​不是则为0。

我试过这样做：

df_sen = read.csv("df.csv", sep = ";",header = TRUE) 
df_triggers = read.csv("df.csv", sep = ";",header = TRUE) 
dat <- data.frame(v=df_sen$sentence)
matrix <- grepl(df_triggers$trigger, dat$v)
write.csv(matrix,file = "matrix.csv")

但是我看到错误消息，我在grepl（）中有多个模式。

所需的输出是：

                                 few days    few millions
"She would like to go there"        0              0
"I had it few days ago"             1              0
"We have spent few millions         0              1

你可以帮助我达到这样的效果吗？
