Size vector must have at least two elements
WebbAn atomic vector is the simplest R data type and it is a linear vector of a single type, e.g. all numbers. Above, we saw 2 of the 6 main atomic vector types that R uses: "character" and "numeric" (or "double"). These are the basic building blocks that all R objects are built from. The other 4 atomic vector types are: WebbThe direct answer to the question is you use table on the pair of factors you want to test (e.g. Group and race) and then use that as input to chisq.test e.g. (you'll note that each group is a different size - e.g. group 1 has 46 people, group 5 has 32) # do the chi-square chisq.test(mytab) Pearson's Chi-squared test data: mytab X-squared = 6.0928, df = 8, p …

WebbWe can set the size of a Vector using setSize () method of Vector class. If new size is greater than the current size then all the elements after current size index have null values. If new size is less than current size then the elements after current size index have been deleted from the Vector.

WebbThere are four types of index vectors: Logical index vector. Positive-integral index vector. Negative-integral index vector. Character index vector. Let us look at these different indexing techniques: 1. Logical index vectors. We can use a vector of logical values to index another vector of the same length. Webb8 juni 2011 · The vector size is the total number of elements of a vector and it is always the same for all compilers. Vectors are re-sizeable. The capacity is the maximum …
WebbWe can calculate its arc length by from t = 0 to t = 4 using the formula, L = ∫ a b r ′ ( t) x d t, where r ′ ( t) represents the tangent vector. This means that we’ll need to find r ′ ( t) by differentiating each of the vector function’s component. WebbA vector is nothing else than a sequence of elements of a certain type. R distinguishes vectors with two different modes. Atomic vectors: All elements must have the same basic type (e.g., numeric, character, …). Lists: Special …
