Example 1: Check if two vectors are identical The code below demonstrates how to compare two strings in R to see if they are equal. How to Read rda file in R (with Example) » finnstats Now we can define two strings string1 <- "Hello" string2 <- "hello" ...
How to compare variances in R To compare two variances, use the R function var.test() as follows: Method 1 var.test(values ~ groups, data, alternative = "two.sided") Method 2 var.test(x, y, alternative = "two.sided") x,y: numeric vectors ...

This method provides a straightforward way to assess the correlation between your distance matrices. Here is how you can do it: Convert your distance matrices into vectors excluding the diagonal (zero) elements using the squareform function. Calculate Spearman's rho between these two vectors t...
To toggle this, we use the flag var.equal=TRUE. In the three examples shown here we’ll test the hypothesis that Clevelanders and New Yorkers spend different amounts monthly eating out. The first example assumes that we have two numeric vectors: one with Clevelanders' spending and one with ...
# save the vectors in a new matrix word_model = wv_keras vector_size = word_model.wv.vectors[1].shape[0] embedding_matrix = np.zeros((len(word_model.wv.vocab) + 1, vector_size)) for i, vec in enumerate(word_model.wv.vectors): embedding_matrix[i] = vec # Get list of texts ...
In the figure, ServerA and ServerB are direct replication partners, as are ServerB and ServerC. Although changes that originate on ServerA are eventually replicated to ServerC, these two servers do not have a direct connection to each other, so they are known as transitive replication ...

How to Calculate Mean Absolute Error in R, here we are exploring two possible ways. Approach 1: Calculate Mean Absolute Error Between Two Vectors For approach 1 we can make use of the Metrics package. Let’s load the library first. library(Metrics) Now we need observed and predicted observa...
%in% in r, with value 8 %in% ChickWeight$Time [1] TRUE Comparing two vectors using the percent in percent operator The percent in percent operator can be used to compare two vectors. It will return an array with the same number of elements as the initial vector, each of which will indica...
