deaR expeRts,

I have the following data

> dput(Tuto)
structure(list(X = c(-114.028, -114.011, -114.442, -113.937,
-114.187, -114.083, -113.949, -114.15, -114.068, -114.203, -113.958,

-114.048, -114.188, -114.129, -114.071, -113.934, -114.001, -114.075,

-114.119, -113.954, -114.051, -113.988, -114.194, -114.025),
    Y = c(51.431, 51.279, 51.167, 51.165, 51.155, 51.14, 51.126,
    51.126, 51.116, 51.115, 51.092, 51.091, 51.084, 51.082, 51.076,

    50.907, 50.877, 50.877, 50.86, 50.854, 50.826), a = c(0.838,
    0.901, 0.953, 0.902, 0.782, 0.938, 0.884, 0.879, 0.932, 0.947,
    0.965, 0.828, 0.923, 0.892, 0.884, 0.897, 0.912, 0.988, 0.901,
    0.855, 0.999, 0.846, 0.845, 0.798, 0.749, 0.753, 0.762, 0.646,
    0.729, 0.544, 0.265, 0.449, 0.334, 0.36, 0.325, 0.337, 0.249,
    0.114, 0.149, 0.173, 0.175, 0.184, 0.219, 0.106, 0.148),
    n = c(0.653, 0.625, 0.641, 0.63, 0.656, 0.619, 0.628, 0.634,
    0.63, 0.604, 0.598, 0.617, 0.632, 0.635, 0.637, 0.646, 0.619,
    0.613, 0.63, 0.615, 0.604, 0.639, 0.598, 0.593, 0.583, 0.606,
    0.594, 0.653, 0.63, 0.577, 0.624, 0.626, 0.676, 0.641, 0.629,
    0.579, 0.603, 0.607, 0.66, 0.614, 0.618, 0.574, 0.552, 0.62,
    0.599)), row.names = c(19L, 22L, 18L, 3L, 45L, 20L, 14L,
43L, 40L, 44L, 37L, 12L, 42L, 41L, 39L, 38L, 33L, 8L, 36L, 16L,
32L, 31L, 5L, 34L, 35L, 9L, 13L, 30L, 29L, 4L, 24L, 27L, 28L,
23L, 25L, 21L, 26L, 6L, 15L, 2L, 1L, 7L, 11L, 10L, 17L), class = "data.frame")

In the given data,

X-> Latitude

Y-> Longitude

a-> Factor 1

n-> Factor 2

I want to draw a raster map of these values within the following limits  (xmn=-114.5, xmx=-113.7, ymn=50.800, ymx=51.600). I have tried through "raster" library but failed as I wasn't able to properly generate the data.
I will be thankful if I can get any kind of help. Thank-you very much in advance.

Eliza
