有人知道R中的DT数据表中是否可以进行批量关键字搜索吗?例如,在下面的代码中,是否可以在搜索框中搜索3辆特定汽车?理想情况下,我想立即在搜索框中粘贴“马自达RX4”,“ Merc 230”,“菲亚特128”,然后在下表中查看结果,而不必分别进行搜索。我从事生物信息学工作,我的同事希望在交互式表格中搜索特定的蛋白质/基因等列表,而不必分别粘贴每个列表。
示例代码:
## example taken from https://rstudio.github.io/DT/007-search.html
library(DT)
mtcars2 = mtcars[, c(1:5, 9)]
mtcars2$am = factor(mtcars$am, c(0, 1), c('automatic', 'manual'))
# search for Ma or Me
dt <- datatable(
mtcars2, colnames = c('model' = 1),
filter = list(position = 'top', clear = FALSE),
options = list(
search = list(regex = TRUE, caseInsensitive = TRUE),
pageLength = 5
)
)
## simple Shiny app with datatable
ui <- fluidPage(
fluidRow(
DT::dataTableOutput("table")
)
)
server <- function(input, output) {
output$table <- DT::renderDataTable(dt)
}
shinyApp(ui = ui, server = server)
