r - 创建一个包含一行和多列的数据框

Question

我想创建一个 12 列和 1 行的数据框。我有这个数据:

Tissues <-
 [1] "ova"                      "testes"                   "optic_lobe"               "retina"                   "suckers"                 
 [6] "subesophageal_brain"      "Supraesophageal_brain"    "skin"                     "stage15tissues"           "axial_nerve_corde"       
[11] "posterior_salivary_gland" "viscera"                 
 reads <-
 [1] 22444744 30671024 22648756 24002307 26438055 48999389 60168243 30172728 26812536 23359754 24038817 25570689

我想创建这个:

       tissue1 tissue2 tissue3 tissue4 tissue5 tissue6 etc..
reads       1       2       3        4      5        6  

我已经尝试过:

df <- data.frame(matrix(ncol = 12, nrow = 1))
x <- TESSUTI
colnames(df) <- x

但是如何将读数添加到每列？

有人可以帮助我吗？

有一个可重现的示例很有帮助，我们可以轻松复制和粘贴。

这是一个解决方案:

##Your input data
tissues <- letters[1:12]
reads <- rnorm(n = 12,mean = 250000,sd = 1000)

##Put the reads into one row of a matrix, then convert to dataframe
data <- data.frame(matrix(nrow = 1,data = reads))

##set the colnames to match your tissue, and the reads row to have a reads name
colnames(data) <- tissues
rownames(data) <- 'reads'

print(data)
           a      b      c      d      e      f      g      h      i      j      k      l
