> class(as.numeric(crsp)) 1 'numeric' you can also see the difference in available methods: One of the features of a time series is that the time values are hidden inside of it.
Also, because read.csv converts strings to factors by default, wt is a vector of class factor. The correlation coefficient ( ρ) is a measure that determines the degree to which the movement of two different variables is associated. The most common correlation coefficient, generated by the Pearson product-moment correlation, is used to measure the linear relationship between two variables. However, in a non-linear relationship, this correlation coefficient may not always be a suitable measure of dependence. now if you want to compare it with a 'numeric' object, then just use 'as.numeric'. If so, R is treating the data as strings, rather than numbers. Calculating the correlation coefficient is time-consuming, so data are often plugged into a calculator, computer, or statistics program to find the coefficient.A negative correlation, or inverse correlation, is a key concept in the creation of diversified portfolios that can better withstand portfolio volatility.Its wireless and features a rechargeable battery that will power your keyboard for. A value of zero indicates no relationship between the two variables being compared. The numeric keypad is also ideal for spreadsheets and finance applications.A correlation coefficient greater than zero indicates a positive relationship while a value less than zero signifies a negative relationship. to insert the euro currency symbol, hold down Alt and press 0128 on the numeric keypad.Correlation coefficients are used to measure the strength of the linear relationship between two variables.
