Question

我正在使用以下代码加载多个软件包。

!=

它会在加载消息后打印

.Select(p => new ProductViewModel()
{
    Id = p.id,
    Name = p.name,
    Description = p.description,
    Rating = p.rating,
    Price = p.offer != null ? p.offer.sale_price : p.price
});

我尝试了Packages <- c("gridExtra", "scatterplot3d", "plot3D", "gridExtra", "plyr", "ggplot2", "magrittr", "reshape2", "data.table") lapply(Packages, library, character.only = TRUE)和## [[1]] ## [1] "gridExtra" "stats" "graphics" "grDevices" "utils" "datasets" ## [7] "methods" "base" ## ## [[2]] ## [1] "scatterplot3d" "gridExtra" "stats" "graphics" ## [5] "grDevices" "utils" "datasets" "methods" ## [9] "base" ## ## [[3]] ## [1] "plot3D" "scatterplot3d" "gridExtra" "stats" ## [5] "graphics" "grDevices" "utils" "datasets" ## [9] "methods" "base" ## ## [[4]] ## [1] "plot3D" "scatterplot3d" "gridExtra" "stats" ## [5] "graphics" "grDevices" "utils" "datasets" ## [9] "methods" "base" ## ## [[5]] ## [1] "plyr" "plot3D" "scatterplot3d" "gridExtra" ## [5] "stats" "graphics" "grDevices" "utils" ## [9] "datasets" "methods" "base" ## ## [[6]] ## [1] "ggplot2" "plyr" "plot3D" "scatterplot3d" ## [5] "gridExtra" "stats" "graphics" "grDevices" ## [9] "utils" "datasets" "methods" "base"，但没有解决问题

suppressWarnings

我查看了这些STO帖子，但它们没有帮助enter link description here enter link description here

此“消息”是lapply命令的返回值。如果您不想看到此信息，请将结果分配给变量。

x <- lapply(Packages, library, character.only = TRUE)

禁止显示多个软件包/库加载消息
