Mr McHaggis,
I'm not sure what " i'm having issues when it comes to reading my
data in rows rather than columns " means, but here's some thoughts on
your problem:
ExData <- structure(list(Noun = c(21L, 26L, 31L, 37L, 22L, 12L, 22L, 12L,
27L, 20L, 21L, 29L, 16L, 23L, 29L, 33L, 29L, 24L, 28L, 32L, 19L,
19L, 19L, 29L, 34L, 27L, 13L, 17L, 21L, 28L), Verb = c(4L, 4L,
6L, 4L, 3L, 8L, 5L, 11L, 7L, 4L, 6L, 1L, 19L, 6L, 5L, 7L, 4L,
7L, 2L, 5L, 6L, 7L, 4L, 8L, 9L, 9L, 11L, 7L, 6L, 4L), adverb = c(9L,
5L, 6L, 6L, 1L, 0L, 0L, 0L, 1L, 1L, 1L, 0L, 0L, 2L, 0L, 0L, 0L,
0L, 1L, 0L, 0L, 3L, 1L, 3L, 0L, 1L, 5L, 0L, 0L, 0L), Adjective = c(1L,
3L, 0L, 0L, 10L, 9L, 5L, 12L, 10L, 10L, 6L, 8L, 8L, 5L, 2L, 3L,
2L, 7L, 3L, 7L, 5L, 4L, 5L, 4L, 1L, 3L, 9L, 10L, 7L, 5L), Preposition = c(1L,
0L, 0L, 0L, 0L, 0L, 0L, 0L, 0L, 1L, 0L, 0L, 0L, 0L, 0L, 0L, 0L,
1L, 0L, 0L, 0L, 0L, 1L, 0L, 0L, 0L, 0L, 0L, 0L, 0L), Total = c(36L,
38L, 43L, 47L, 36L, 29L, 32L, 35L, 45L, 36L, 34L, 38L, 43L, 36L,
36L, 43L, 35L, 39L, 34L, 44L, 30L, 33L, 30L, 44L, 44L, 40L, 38L,
34L, 34L, 37L)), .Names = c("Noun", "Verb", "adverb", "Adjective",
"Preposition", "Total"), class = "data.frame", row.names = c("1",
"2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13",
"14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24",
"25", "26", "27", "28", "29", "30"))
x1 <- data[1, 1:5] ## Why do you use c() here to combine a single line
with itself? This actually converts your data frame to a list, which
causes your problem
shapiro.test(x1) ## Still will not work because data frames don't
coerce to vectors, perhaps you meant to just extract the values, in
which case you need to add
shapiro.test(as.numeric(x1))
# but it seems more likely that you mean to get a column's worth of data:
shapiro.test(ExData[1:5,1])
Does this help?

If you have some basic programming background, take a look at chapter
2 of the R language definition to get a solid explanation of what all
this talk of numeric/atomic/data frame/list is going on about.
