A class of plant genes conferring resistance to a specific strain (or group of strains) of a particular pathogen. Their primary function is to sense the presence of the pathogen and to trigger the defence pathways in the plant. R genes have been cloned from a number of plant species.

R-squared is a statistical measurement that determines the proportion of a security's return, or the return on a specific portfolio of securities, that can be explained by variations in the stock market, as measured by a benchmark index.
For example, an r-squared of 0.08 shows that 80% of a security's return is the result of changes in the market - specifically that 80% of its gains are due to market gains and 80% of its losses are due to market losses. The other 20% are the result of factors particular to the security itself.

A measure of the capacity of a material to resist heat transfer. The R-Value is the reciprocal of the conductivity of a material (U-Value). The larger the R-Value of a material, the greater its insulating properties.
