Question

我想将R中的分析输出与某人作为txt文件共享。我在这里可以做到这一点，我知道：

write.table(S$MainInformation,  file = "Output.txt",
  row.names = FALSE, sep = "\t", 
  quote = FALSE, fileEncoding = "UTF-8", append = TRUE)

write.table(S$AnnualProduction,  file = "Output.txt",
  row.names = FALSE, sep = "\t", 
  quote = FALSE, fileEncoding = "UTF-8", append = TRUE)

write.table(S$AnnualGrowthRate,  file = "Output.txt",
  row.names = FALSE, sep = "\t", 
  quote = FALSE, fileEncoding = "UTF-8", append = TRUE)

write.table(S$MostProdAuthors,  file = "Output.txt",
  row.names = FALSE, sep = "\t", 
  quote = FALSE, fileEncoding = "UTF-8", append = TRUE)

因此将文档合并为一个txt文件。但是，如果我想一步完成，即S而不是S$，我会得到一个错误代码，毫不奇怪，这个代码意味着不同的行数。

write.table(S,  file = "Output.txt",
   row.names = FALSE, sep = "\t", 
   quote = FALSE, fileEncoding = "UTF-8")

错误（函数（...，row.names = NULL，check.rows = FALSE，check.names = TRUE，：参数意味着不同的行数：16,25,1,10

当然，我并不关心...我还不知道如何使用lapply这可能会有所帮助_谢谢！ SCW

Answer 1

文件主要是人类可读还是机器可读？

如果人类可读，则上面建议的capture.output()就足够了。

lst <- list(a=1:8, 
            b=1.2e+11, 
          df1=data.frame(foo=1:5/4, bar=1:5/3), 
          df2=as.data.frame(matrix(runif(16), 4)))
capture.output(lst, file="list.txt")

否则，如果你坚持并排放置东西，这可能是一个选择

max_l <- max(rapply(lst, length))
as.data.frame(rapply(lst, function(x) 'length<-'(x, max_l), how="list"))

#    a       b df1.foo   df1.bar    df2.V1    df2.V2    df2.V3     df2.V4
# 1  1 1.2e+11    0.25 0.3333333 0.3978436 0.1971467 0.5619881 0.01103607
# 2  2      NA    0.50 0.6666667 0.9556758 0.1153423 0.7327180 0.90631526
# 3  3      NA    0.75 1.0000000 0.6533494 0.9959655 0.8708056 0.77065363
# 4  4      NA    1.00 1.3333333 0.3287437 0.3792767 0.5721703 0.38250462
# 5  5      NA    1.25 1.6666667        NA        NA        NA         NA
# 6  6      NA      NA        NA        NA        NA        NA         NA
# 7  7      NA      NA        NA        NA        NA        NA         NA
# 8  8      NA      NA        NA        NA        NA        NA         NA

然后将其作为任何其他data.frame写入文件。

如果文件主要是机器可读的，可能使用其他软件进一步处理结果，更好的方法是使用比纯文本更专业的文件格式。类似于JSON或XML。

写入JSON就像

一样简单

library(RJSONIO)
write(toJSON(lst), file="list.json")

我认为结果文件仍然具有人类可读性。

{
"a": [ 1, 2, 3, 4, 5, 6, 7, 8 ],
"b": 1.2e+11,
"df1": {
 "foo": [   0.25,    0.5,   0.75,      1,   1.25 ],
 "bar": [ 0.33333, 0.66667,      1, 1.3333, 1.6667 ] 
},
"df2": {
 "V1": [ 0.094046, 0.049654, 0.82116, 0.82932 ],
 "V2": [ 0.65473, 0.13283, 0.34181, 0.73137 ],
 "V3": [ 0.90729, 0.6962, 0.24158, 0.64411 ],
 "V4": [ 0.28075, 0.95764, 0.1584, 0.41834 ] 
} 
}

Write.table作为具有不同行数的文本文件
