Therefore, in case we need to get the PMIDs of the retrieval, we can do so by getting values for the id component of the cancer object with the following code: > cancer@id One important point that should be noted is that this query retrieved only the first 1000 hits out of 575,447 (the default value for retmax). Furthermore, one should follow the policies for its uses to avoid overloading the E-Utilities server. gov/books/NBK25497/. Now, we are left with the creation of a RISmed object (the same as the myeloma object).

To illustrate, when we need to compare a group against a hypothetical value and our measurements follow the Gaussian distribution, we can use a one-sample t-test. However, if we have two paired groups (both measurements that follow the Gaussian distribution) being compared, we can use a paired t-test. R has built-in functions to carry out such tests, and in this recipe, we will try out some of these. 23 Starting Bioinformatics with R How to do it… Use the following steps to perform a statistical test on your data: 1.

Rm argument to TRUE, and the computation will be done only based on non-NA values. 2 We see here that in the case of missing values, the mean function returns NA by default as it does not know how to handle the missing value. 2. To compute the correlation between the sepal length and sepal width in our iris data, we simply use the cor function with the two columns (sepal length and sepal width) as the arguments for the function. We can compute the different types of correlation coefficients, namely Pearson, Spearman, Kendall, and so on, by specifying the apt value for the method arguments in the function.
