关于trackVis的问题

[Zh-MicroSat]

我在使用trackVis遇到了一定的问题，我的代码如下：

file <- list.files(pattern = '.bw') data <- loadBigWig(file) save(data,file = 'Data.rda') load('Data.rda') mybw <- data trackVis(bWData = mybw,chr = "Wnk4",region.min = 101167654,region.max = 101168235) 错误信息如下所示： Error in combine_vars(): ! Faceting variables must have at least one value Run rlang::last_error() to see where the error occurred. Warning messages: 1: In min(x) : no non-missing arguments to min; returning Inf 2: In max(x) : no non-missing arguments to max; returning -Inf 详细展开错误信息如下： <error/rlang_error> Error in combine_vars(): ! Faceting variables must have at least one value

粗体部分似乎为主要问题，期待您的回复
