Question

有没有人试图将R对象转换为文本文件？我有从Seqmeta包创建的R对象，我正在尝试将其转换为文本文件

load("variant.Rdata")
write.csv(variants, file="variants.csv")
Error in as.data.frame.default(x[[i]], optional = TRUE, stringsAsFactors = stringsAsFactors) :
  cannot coerce class ""seqMeta"" to a data.frame

然后我试了

dump(variant, file="variant_file")
Error in FUN(X[[1L]], ...) : invalid first argument

如何将数据转换为csv格式？

Answer 1

如果需要保存通用R对象，通常使用saveRDS（这对于单个对象使用save更为可取）。如果文件必须是ASCII，则saveRDS，save和serialize都具有参数ascii=TRUE，其中serialize生成最可读的输出。

如果您需要该文件是人类可读的ASCII，则您使用dump走在正确的轨道上。您需要的唯一更改是dump将对象的名称作为其参数：

dump('variant', file="variant_file")

以下是随机神经网络的每个选项的输出类型示例：

> serialize(model,connection = (con<-file('nn','w')),ascii = TRUE)
NULL
> close(con)
> writeLines(readLines('nn',n=10))
